                                 4/9/2001
                                 --------
[bash-2.05 released]

                                   4/10
                                   ----
redir.c
        - check return value of fclose() in write_here_document() for error
          returns; don't just rely on fwrite() failing

support/bashbug.sh
        - set TMPDIR to /tmp if it's null or unset
        - use $TMPDIR in the TEMP tempfile name template
        - fixed the call to `mktemp', if it exists, to make it more portable

jobs.c
        - if WCONTINUED is not defined, define it to 0 and add a define for
          WIFCONTINUED(wstatus) which expands to 0
        - add WCONTINUED to the flags passed to waitpid(2) in waitchld()
        - don't increment children_exited if waitpid's status is WIFCONTINUED,
          since we don't want to call a SIGCHLD trap handler in this case
        - in waitchld(), we set child->running to 1 if WIFCONTINUED(status)
          is non-zero
        - make sure pretty_print_job doesn't check for the core dump bit if
          the process has been continued; it's only valid if the job is dead
        - in set_job_status_and_cleanup, set the job to JRUNNING if job_state
          is non-zero and the job was previously marked as JSTOPPED

configure.in
        - add -DBROKEN_DIRENT_D_INO to interix LOCAL_CFLAGS

lib/glob/glob.c
        - if BROKEN_DIRENT_D_INO is defined, define REAL_DIR_ENTRY to 1

jobs.c
        - in kill_pid, we only need to block and unblock SIGCHLD if the
          `group' argument is non-zero, since otherwise we just call `kill'
          on the pid argument

version.c
        - update copyright date to 2001

bashline.c
        - prog_complete_return needs to take a `const char *' as its first
          argument
        - history_completion_generator needs to take a `const char *' as
          its first argument, and `text' needs to be a `const char *'

                                   4/11
                                   ----
redir.c
        - fixed a weird typo in redir_special_open, case RF_DEVFD, added
          call to all_digits before call to legal_number
        - fixed do_redirection_internal to call legal_number instead of atol(3)
          when translating r_duplicating_{in,out}put_word, so it handles
          overflow better
        - produce an error message in redirection_error for out-of-range
          file descriptors
        - change allocation strategy in redirection_error so we don't have to
          malloc scratch memory if redirection_expand() fails

jobs.h
        - added defines for `running' member of a struct process

general.c
        - fix legal_number to return 0 when strtol(3) reports overflow or
          underflow

parse.y
        - changed read_token_word to call legal_number instead of atoi(3)

input.c
        - return -1/EBADF from close_buffered_fd if fd is < 0

command.h
        - fixed bogus comment about IS_DESCRIPTOR in description of the
          REDIRECTEE struct

print_cmd.c
        - change cprintf's 'd' modifier code to display negative numbers as
          an out-of-range value.  We can do this only because the only use
          of %d is to output file descriptor numbers in redirections

support/mksignames.c
        - need to include config.h to get a possible value for
          UNUSABLE_RT_SIGNALS

                                   4/16
                                   ----
lib/readline/doc/rluser.texinfo
        - corrected a small error in one description of M-DEL

                                   4/17
                                   ----
stringlib.c
        - need to initialize `ind' before calls to RESIZE_MALLOCED_BUFFER
          in strcreplace()

support/bashversion.c
        - new file, prints bash version information

Makefile.in
        - rules for building bashversion and linking it to version.o

                                   4/24
                                   ----
conftypes.h
        - new file with HOSTTYPE, OSTYPE, MACHTYPE, etc. defines from
          variables.h

variables.h, version.c
        - include conftypes.h

patchlevel.h
        - new file, contains define for PATCHLEVEL.  Doing away with the old
          scheme of having the information in configure.in

version.c
        - include patchlevel.h

Makefile.in
        - run bashversion -p to find patch level rather than have configure
          substitute in a value
        - pass -S ${top_srcdir} to support/mkversion.sh

support/mkversion.sh
        - don't put PATCHLEVEL define into version.h, but accept and ignore
          a -p option
        - take a new -S srcdir option
        - find the patch level by parsing it out of patchlevel.h

configure.in
        - hard-code BASHVERS assignment instead of reading it from a file
        - remove BASHPATCH; don't substitute it

_distribution,_patchlevel
        - removed

                                   4/26
                                   ----
shell.c
        - call init_noninteractive() in open_shell_script if forced_interactive
          is non-zero (the shell was started with -i) and fd_is_tty is 0
          (the script file is a real file, not something like /dev/stdin),
          since it wasn't done earlier

builtins/printf.def
        - change for POSIX.2 compliance when conversion errors are encountered
          when processing %d, %u, and floating point conversion operators
          (print a warning message, return the value accumulated at the time
          of the error -- which is always 0 -- and exit with a non-zero status)

command.h
        - added CMD_COMMAND_BUILTIN for use by the `command' builtin and the
          code in execute_cmd.c

builtins/command.def
        - add CMD_COMMAND_BUILTIN to the created command's flags

                                    5/1
                                    ---
configure.in
        - add call to AC_C_CONST to test `const' compiler behavior
        - add call to AC_C_INLINE to test `inline' compiler behavior
        - add call to AC_C_STRINGIZE to test cpp #x stringizing operator

config.h.in
        - add `#undef const' for configure to substitute
        - add `#undef inline' for configure to substitute
        - add `#undef HAVE_STRINGIZE' for configure to substitute

include/stdc.h
        - remove code that defines or undefines `const' and `inline'
        - change the __STRING macro to be defined depending on the value
          of HAVE_STRINGIZE

lib/malloc/malloc.c
        - change the __STRING macro to be defined depending on the value
          of HAVE_STRINGIZE

lib/readline/{readline,rlprivate}.h
        - moved rl_get_termcap to readline.h, making it a public function

lib/readline/readline.h
        - new #define, RL_READLINE_VERSION, hex-encoded library version
          number, currently set to 0x0402
        - new public int variable, rl_readline_version

lib/readline/readline.c
        - #define RL_READLINE_VERSION if it is not already defined (which it
          should be in readline.h)
        - initialize rl_readline_version to RL_READLINE_VERSION

lib/readline/doc/rltech.texinfo
        - documented rl_get_termcap
        - documented rl_readline_version

jobs.c
        - job_exit_status should return an int, not a WAIT (undetected
          before because on most POSIX-like systems a WAIT is really an int)

builtins/evalfile.c
        - added FEVAL_REGFILE (file must be a regular file) to accepted
           _evalfile flags
        - fc_execute_file() adds FEVAL_REGFILE to _evalfile flags.  This
          means that startup files and files read with `.' no longer need
          to be regular files

                                    5/2
                                    ---

lib/termcap/Makefile.in
        - fix target for installed termcap library (normally unused)

lib/tilde/Makefile.in
        - fix install target to install in $(libdir) (normally unused)

Makefile.in
        - don't make $(man3dir) since there's nothing installed there

Makefile.in,doc/Makefile.in
        - change `man1ext' to `.1', `man3ext' to `.3'
        - change appropriate install targets to use new values of man[13]ext
        - use `test ...' instead of `[...]'
        - add support for DESTDIR root installation prefix, for package
          building (installdirs, install, install-strip, uninstall targets)

builtins/common.c
        - new function int get_exitstat(WORD_LIST *list) returns an eight-bit
          exit status value for use in return, exit, logout builtins

builtins/common.h
        - extern declaration for get_exitstat()

builtins/{exit,return}.def
        - call get_exitstat where appropriate

builtins/printf.def
        - add support for "'" flag character as posix 1003.2-200x d6 says
        - fix core dump when user-supplied field width or precision is 0
        - fix to printstr() to handle zero-length precision with `%b' format
          specifier (printf '%.0b-%.0s\n' foo bar)
        - fix to printstr() to treat a negative field width as a positive
          field width with left-justification
        - fix to mklong to avoid static buffers, which can always be overrun
          by someone sufficiently motivated

bashline.c
        - change var in add_host_name to type `size_t' for passing to xrealloc

                                    5/3
                                    ---
execute_cmd.c
        - change restore_signal_mask to accept a sigset_t *, since a sigset_t
          may not fit into a pointer, change call

unwind_prot.c
        - use a union UWP in restore_variable when restoring a variable whose
          size is the same as sizeof(int), the reverse of the method used to
          store it in unwind_protect_int

builtins/printf.def
        - use a #define LENMODS containing the length modifiers instead of
          testing against each possible modifier character, save any mod
          character found
        - add support for ISO C99 length specifiers `j', `t', and `z'
        - if `L' modifier is supplied with a floating point conversion char,
          pass a `long double' to printf if HAVE_LONG_DOUBLE is defined

configure.in,config.h.in
        - call AC_C_LONG_DOUBLE to check for `long double'; define
          HAVE_LONG_DOUBLE if supported

bashline.c
        - fix an inadvertantly-unclosed comment in attempt_shell_completion
        - make set_saved_history return a value
        - make dynamic_complete_history return a useful value

{make_cmd,execute_cmd,shell,subst,trap,variables,input,unwind_prot,test,
pcomplete}.c
        - removed some declared-but-unused variables

builtins/{cd,enable,fc,set,setattr,type,umask,printf,complete}.def
        - removed some declared-but-unused variables

lib/sh/{zread,netopen}.c
        - removed some declared-but-unused variables

execute_cmd.c
        - in execute_arith_command, use a long variable to hold the result
          of evalexp(), since that's what it returns

builtins/evalstring.c
        - make cat_file return -1 on a read or write error

lib/sh/stringlib.c
        - make merge_stringlists() return the right value

                                    5/7
                                    ---
pcomplete.c
        - remove typo that caused empty declaration (;;)

parse.y
        - fix yyerror() to accept a single string argument; fix callers

trap.c
        - cast pointer to long instead of int when printing message with
          internal_warning() in run_pending_traps()

subst.c
        - fix process_substitute to handle stdin being closed

test.c
        - change `while' to `if' in and() and or(), since the loop isn't
          actually performed -- there's an unconditional `return' in the
          loop body
        - check for integer overflow of arguments to `-t'

lib/sh/netopen.c
        - change _getserv() to reject negative port/service numbers

expr.c
        - fix strlong() to not convert the base specification from long to
          int before checking for overflow, since truncation on machines
          where sizeof(int) != sizeof(long) may mask errors

builtins/{jobs,kill,wait}.def
        - use legal_number instead of atoi when converting strings to pid_t;
          check for numeric overflow

input.c
        - fix for cygwin in b_fill_buffer -- off-by-one error when checking
          buffer for \r\n termination

general.h
        - new #define INT_STRLEN_BOUND(t), computes max length of string
          representing integer value of type T, possibly including a sign
          character
        - include <limits.h> if it's present

{execute_cmd,findcmd,test}.c
        - don't include <limits.h>, since general.h does it now

{execute_cmd,lib/sh/itos,pcomplete,print_cmd,subst,variables}.c
        - use INT_STRLEN_BOUND instead of static array sizes when converting
          various strings to integer values

shell.h
        - struct fd_bitmap now uses an `int' size, since it's bounded by
          the number of file descriptors, which must fit into an `int'

execute_cmd.c
        - FD_BITMAP_DEFAULT_SIZE is now 32, not 32L
        - new_fd_bitmap takes an `int' size parameter, not a `long'

execute_cmd.h
        - change prototype for new_fd_bitmap()

test.c
        - fix test_stat to check for overflow when parsing the integer file
          descriptor number; return ENOENT instead of EBADF for files that
          are not open

hashlib.c
        - don't discard the upper 32 bits of the random value, if present

lib/readline/shell.c
        - use the same INT_STRLEN_BOUND mechanism to decide how much space to
          allocated in sh_set_lines_and_columns

                                    5/8
                                    ---
aclocal.m4
        - add check for libtinfo (termcap-specific portion of ncurses-5.2) to
          BASH_CHECK_LIB_TERMCAP
        - new macro, RL_LIB_READLINE_VERSION, checks version of installed
          readline library and (optionally) writes version #defines to
          config.h.  Bash doesn't use the version defines

configure.in
        - call RL_LIB_READLINE_VERSION instead of support/rlvers.sh

execute_cmd.c
        - fix execute_shell_script and the WHITECHAR and STRINGCHAR macros
          to check array bounds before indexing into the sample string

unwind_prot.[ch]
        - import new versions submitted by Paul Eggert <eggert@twinsun.com>
          with a couple of changes for backwards compatibility, so the rest
          of the source doesn't need to be changed yet

jobs.c
        - use unwind_protect_var on last_made_pid in run_sigchld_trap

builtins/bind.def
        - use unwind_protect_var on rl_outstream

general.c
        - rework print_rlimtype to use INT_STRLEN_BOUND and handle the
          most negative number correctly

expr.c
        - `tokval' should have been a `long', since all arithmetic is done
          as longs

builtins/history.def
        - consolidate tests for valid history position in one block to
          avoid duplicate code and strings

builtins/ulimit.def
        - fix check for overflow when setting limit to work when int is 32
          bits and RLIMTYPE is 64

lib/sh/tmpfile.c
        - don't truncate the result of time(3) to int; just use time_t,
          since it's being assigned to an `unsigned long'

mailcheck.c
        - use legal_number instead of atoi in time_to_check_mail() to catch
          more numeric errors; consolidate error checking in one block
        - last_time_mail_checked should be a time_t

                                    5/9
                                    ---
builtins/set.def
        - recognize `set [-+]o nolog' if HISTORY is defined

bashline.c
        - new variable `dont_save_function_defs', set by `set -o nolog';
          currently ignored

command.h
        - the `dest' member of a REDIRECTEE is now an `int'

parse.y,redir.c
        - changed uses of `redir.test' (where redir is a REDIRECTEE) since
          it's now an int

lib/readline/rlstdc.h
        - don't mess around with `const', rely on configure to supply a
          proper definition if the compiler doesn't support it

lib/tilde/tilde.h
        - include <config.h> if HAVE_CONFIG_H is defined
        - don't mess around with `const', rely on configure

builtins/shopt.def
        - new read-only `shopt' option, login_shell, non-zero if shell is a
          login shell (as decided by shell.c)
        - new function set_login_shell(), sets shopt private value of
          login_shell

builtins/common.h
        - new extern declaration for set_login_shell

        - call set_login_shell after setting value of login_shell (in
          main() and set_shell_name())

        - added new `\A' prompt string escape sequence:  time in 24-hour
          HH:MM format

configure.in, config.h.in
        - check for <grp.h>, define HAVE_GRP_H if found

        - extern declaration for _rl_match_hidden_files

builtins/hash.def
        - new `-t' option to list hash values for each filename argument

input.c
        - check for read error before doing \r\n translation on cygnus in
          b_fill_buffer
        - reset bp->b_used to 0 instead of leaving it at -1 on read error
          in b_fill_buffer

builtins/shopt.def
        - new functions, shopt_setopt(name, mode) and
          shopt_listopt(name, mode) to give the rest of the shell an easy
          interface

builtins/common.h
        - extern declarations for shopt_setopt and shopt_listopt

shell.c
        - new invocation options -O and +O, to list or set/unset shopt

lib/sh/zread.c
        - int -> ssize_t fixes to mirror modern declarations of read and write
        - the `off' variable in zsyncfd should be an off_t since it computes
          a file offset
        - the local buffer `lbuf' is now char, since it's not nice to pass
          unsigned char * to read(2), and the values from it are assigned to
          a char anyway
        - lind and lused are now size_t, since they index into a buffer
        - set lused to 0 on read error

lib/sh/zwrite.c

          to pass a `char *' to `write'

builtins/evalstring.c
        - the number of chars read with zread in cat_file should be assigned
          to a variable of type ssize_t

input.c
        - the number of chars read with zread in b_fill_buffer should be
          assigned to a variable of type ssize_t
        - `localbuf' is now type char[], since POSIX says you shouldn't pass
          unsigned char * to read(2)
        - in getc_with_restart(), use a variable of type unsigned char to
          get a value from the local buffer and return it
        - in ungetc_with_restart, explicitly return the character arg passed
          to avoid relying on localbuf being unsigned char

subst.c
        - the number of chars read with zread in read_comsub should be
          assigned to a variable of type ssize_t

mksyntax.c
        - instead of casting to unsigned char * in addcstr, use a variable
          of type unsigned char and let the compiler do the work

parse.y
        - instead of casting to unsigned char * in yy_readline_get, use a
          variable of type unsigned char and let the compiler do the work

          library version for use by the caller
        - change RL_LIB_READLINE_VERSION to not compute ac_cv_rl_prefix if
          the caller has already assigned it a value
        - rename _rl_prefix -> ac_cv_rl_prefix, _rl_libdir -> ac_cv_rl_libdir,
          _rl_includedir -> ac_cv_rl_includedir

configure.in
        - change testing of whether to use the value of
          $opt_with_installed_readline to be != no, to allow the user to
          specify a prefix where the installed readline library may be found
        - if --with-installed-readline=PREFIX is supplied, set ac_cv_rl_prefix
          to PREFIX before calling RL_LIB_READLINE_VERSION
        - if --with-installed-readline[=PREFIX] is supplied, don't set
          RL_LIBDIR and RL_INCLUDEDIR; let RL_LIB_READLINE_VERSION take care
          of it, set RL_INCLUDE=-I${RL_INCLUDEDIR}
        - if --with-installed-readline[=PREFIX] is supplied, and we're
          linking with the history library, assign $RL_LIBDIR to HIST_LIBDIR
          so we use the same version of the installed readline and history
          libraries

Makefile.in, builtins/Makefile.in
        - have configure substitute RL_INCLUDEDIR, set RL_INCLUDEDIR variable

doc/bashref.texi

pcomplete.c
        - changed some function parameters to `const char *' to avoid discarding
          const qualifier

        - make_bare_word, make_word_flags, and make_word now take a
          `const char *' string argument

print_cmd.c
        - cprintf now takes a `const char *' as its first argument, like

        - the conditional define for xprintf should have been HAVE_VPRINTF,
          not HAVE_VFPRINTF

shell.c
        - in isnetconn(), the return value of sizeof() is size_t

aclocal.m4
        - add inclusion of stddef.h if STDC_HEADERS is defined to 1 in
          BASH_CHECK_TYPE

{subst,variables,lib/sh/tmpfile}.c
        - dollar_dollar_pid is now a `pid_t' instead of `int'

variables.c
        - sbrand() now takes an `unsigned long' to set the seed value
        - changed last_random_value to type int, since it's always between
          0 and 32767
        - use strtoul to convert the value in assign_random instead of atoi
        - take out casts in any arguments to sbrand()

          least set the last character in msg_buf to 0 to avoid overrun --
          we really can't do anything about overflow at this point.  if it's

execute_cmd.c
        - in execute_command_internal, keep track of ERR trap and call it if

        - in execute_function, arrange things so the ERR trap is not inherited
          by shell functions, and is saved and restored like the DEBUG trap

doc/{bash.1,bashref.texi}
        - documented new ERR trap

tests/{trap.{tests,right},trap2.sub,trap2a.sub}

subst.c
        - on machines without /dev/fd, change the named pipe fifo list to a

        - don't redefine some is* ctype macros/functions if HAVE_ISXXX is
          defined (meaning that an appropriate function, but not a macro,
          exists)

lib/sh/strtrans.c
        - new function, ansic_shouldquote, returns 1 if argument string
          contains non-printing chars that should be quoted with $'...'

externs.h
        - new declaration for ansic_shouldquote()

variables.c
        - change print_var_value to ansi C quote the string if we're not in
          posix mode and the variable's value contains non-printing chars,
          to use the regular shell single quoting if the value contains
          shell meta-characters, and to just output the string otherwise

lib/sh/shquote.c
        - add `break' to `case '~':' to avoid fallthrough and extra test

doc/bashref.texi
        - note that in POSIX mode, `set' displays variable values that
          include nonprinting characters without quoting, unless they
          contain shell metacharacters

builtins/printf.def, lib/sh/snprintf.c
        - handle `F' conversion specifier as equivalent to 'f'

parse.y, {nojobs,variables}.c
        - a couple of cleanups for when building a minimal configuration

nojobs.c
        - new function: stop_making_children(), just sets
          already_making_children to 0 (like stop_pipeline)

subst.c
        - call stop_making_children from subst.c:command_substitute if
          JOB_CONTROL is not defined.  This fixes the bug where the wrong
          process is waited for (and its status returned) when using
          command substitution in a null command in a shell function

builtins/printf.def
        - new variable `tw' used to keep track of the total number of
          characters written by a single call to `printf' -- to be
          used for the `%n' conversion, which will be added later.  It
          gets reset each time we reuse the format string, which is what
          ksh93 seems to do

                                   -----
variables.c
        - new function, bind_var_to_int (char *var, long val)

variables.h
        - extern declaration for bind_var_to_int

lib/sh/netopen.c
        - use gai_strerror() for error messages when getaddrinfo() fails
        - use PF_INET if DEBUG is defined, since IPv6 doesn't work for me

Makefile.in
        - pass DEBUG=${DEBUG} down to makes in some subdirectories

{builtins,lib{glob,sh}}/Makefile.in
        - append ${DEBUG} to LOCAL_CFLAGS value, passed by top-level Makefile

builtins/printf.def
        - added support for %n format conversion char (number of chars printed
          so far from current format string)

variables.c
        - if posixly_correct is set, the default value of $MAILCHECK is 600
        - use legal_number instead of atoi in adjust_shell_level
        - treat non-numeric assignments to SECONDS as 0 in assign_seconds
        - new function, init_funcname_var; sets FUNCNAME as a dynamic variable
          if it's not set in the initial environment
        - new function, init_groups_var; sets GROUPS as a dynamic array
          variable if it's not set in the initial environment
        - new function, init_dirstack_var; sets DIRSTACK as a dynamic array
          variable if it's not set in the initial environment
        - new function, init_seconds_var; sets SECONDS as a dynamic
          variable using any valid integer value in the initial environment
          as the initial value, as if an assignment had been performed
        - call init_funcname_var, init_groups_var, init_dirstack_var,
          init_seconds_var from initialize_dynamic_variables
        - non-numeric values assigned to LINENO are treated as 0
        - change initialize_shell_variables to not auto-export PATH or TERM
        - change set_home_var to not auto-export HOME
        - change set_shell_var to not auto-export SHELL
        - broke the code that sets HOSTNAME, HOSTTYPE, MACHTYPE, OSTYPE
          out into a separate function, set_machine_vars; none of those
          variables are auto-exported
        - bash no longer un-exports SSH_CLIENT or SSH2_CLIENT

shell.c
        - changed isnetconn() to check SSH_CLIENT and SSH2_CLIENT only if
          SSH_SOURCE_BASHRC is defined in config-top.h

config-top.h
        - added a commented-out definition for SSH_SOURCE_BASHRC

                                   -----
locale.c
        - fixed an `=' vs. `==' typo in set_locale_var when parsing
          LC_NUMERIC

doc/{bash.1,bashref.texi}
        - document what bash does with $POSIXLY_CORRECT

doc/builtins.1
        - some updates

builtins/psize.sh
        - some mktemp(1) changes

lib/readline/readline.c
        - change rl_backward to check for rl_point < 0 and reset to 0 if so

lib/readline/util.c
        - don't compile in _rl_strpbrk if HAVE_STRPBRK is defined

lib/readline/rlprivate.h
        - remove extern declaration of _rl_strpbrk

lib/readline/rldefs.h
        - #define _rl_strpbrk as strpbrk if HAVE_STRPBRK is define, otherwise
          add extern declaration of _rl_strpbrk from rlprivate.h

{mailcheck,shell,variables}.c
        - make sure to include posixtime.h to get any prototype for time(3)
          in scope

{array,eval,execute_cmd,mksyntax,subst}.c, parse.y
builtins/common.c
lib/sh/pathcanon.c
        - a few changes as the result of `gcc -Wall' patches from solar
          designer

builtins/read.def, parse.y
        - change some calls to free() to xfree()

builtins/set.def
        - make sure unset_builtin() resets unset_array to 0 each time through
          the loop, because it's set (and used) depending on the current
          argument

shell.h
        - new define, USE_VAR, to force the compiler to not put a particular
          variable in a register -- helpful if registers are not restored
          by setjmp/longjmp

builtins/{evalfile.c,{read,wait}.def}, {eval,execute_cmd,shell,test}.c
        - use USE_VAR for some variables

subst.c
        - fixed a case in expand_word_internal where a NULL pointer could
          have been passed to free() (though free() should ignore it)
        - fixed a case at the end of expand_word_internal where LIST could
          have been used uninitialized (it makes gcc happy, though it
          doesn't happen in practice)

test.c
        - give test_syntax_error(), beyond(), and integer_expected_error()
          the `__noreturn__' attribute for gcc

unwind_prot.c
        - in clear_unwind_protect_list(), convert `flags' to `long' (via
          assignment to a `long' variable) before casting to `char *', in
          case pointers and longs are 64 bits and ints are 32 (makes no
          difference on 32-bit machines)

                                   -----
print_cmd.c

          to non-const (discarding type qualifier)

{make_cmd,pcomplete,test}.c,parse.y
        - some minor changes to shut up gcc warnings

lib/sh/tmpfile.c
        - fixed sh_mktmpfp to avoid file descriptor leaks in the case that
          sh_mktmpfd succeeds but fdopen fails for some reason
        - change sh_mktmpfd to use the same scheme for computing `filenum'
          as sh_mktmpname
        - change get_sys_tmpdir to prefer P_tmpdir if P_tmpdir is defined
        - changed sh_mktmpname and sh_mktmpfd to avoid trying to assign to
          `nameroot' if `nameroot == 0' (duh)
        - add code to sh_mktmpfd to use mkstemp(3) if USE_MKSTEMP is defined
        - add code to sh_mktmpname to use mktemp(3) if USE_MKTEMP is defined

support/{fixlinks,mkclone}
        - use mktemp if it's available for the symlink test
        - use $TMPDIR instead of hardcoding /tmp; default to /tmp
        - use a better filename for the symlink test instead of `z'

support/bashbug.sh
        - more changes inspired by a patch from solar designer

lib/malloc/Makefile.in
        - new target `alloca', which builds libmalloc.a with alloca.o only
          (for systems without alloca that are configured --without-bash-malloc)

configure.in
        - if we don't have a working alloca and are not configured to build
          the bash malloc library, make a malloc library containing only
          alloca.o

aclocal.m4
        - slight change to RL_LIB_READLINE_VERSION to deal with minor version
          numbers with a letter appended (like 4.2a)

                                   10/31
                                   -----
doc/{bash.1,bashref.texi}
        - slight change to note that only interactive shells resend a SIGHUP
          to all jobs before exiting

externs.h
        - declare strto[ui]max only if NEED_STRTOIMAX_DECL is defined.  This
          keeps picky compilers from choking because intmax_t is not defined
          (MacOS X 10.1)

builtins/printf.def
        - #define NEED_STRTOIMAX_DECL before including shell.h

shell.c
        - fix a problem with $LINENO when executing commands supplied with
          the -c invocation option when ONESHOT is defined

[bash-2.05a-rc1 frozen]

builtins/printf.def
        - fix the %n conversion to require that the variable name supplied
          be a valid shell identifier

variables.c
        - improve random number generator slightly by using the upper 16
          bits of the running random number instead of the lower 16, which
          are incrementally more random

doc/{bash.1,bashref.texi}
        - correct description of POSIXLY_CORRECT to note that the shell enters
          posix mode *before* the startup files are read if POSIXLY_CORRECT
          is in the initial environment

variables.c
        - fix function prologues for init_dirstack_var and init_groups_var
          to agree with caller (no arguments)

jobs.c
        - fix forward function declarations for pipe_read and pipe_close

subst.c
        - removed `inline' attribute from skip_double_quoted because it can
          potentially be called recursively

bashline.c
        - quick fix to bashline.c:attempt_shell_completion programmable
          completion code to just punt if the end of the command word found
          by find_cmd_end is <= the start found by find_cmd_start (the bug
          is probably in find_cmd_start -- fix later)

pcomplete.c
        - fix gen_matches_from_itemlist to return if the stringlist is null
          after any cleaning or initialization, before trying to use it
        - fix GEN_COMPS to only bother to try to append the STRINGLIST
          returned by gen_matches_from_itemlist to `glist' if it's non-NULL

lib/sh/stringlist.c
        - make copy_stringlist return NULL if the STRINGLIST * passed as an
          argument is NULL
        - make append_stringlist call copy_stringlist only if M2 is non-NULL;
          otherwise just return NULL if m1 is NULL
        - make word_list_to_stringlist return 0 immediately if the passed
          LIST argument is NULL
        - make realloc_stringlist call alloc_stringlist if the passed
          STRINGLIST argument (`sl') is 0, just like realloc calls malloc

subst.c
        - in skip_to_delim(), if we have an unclosed ${, and it's at the end
          of the string (string[i] == '{', string[i+1] == '{' and
          string[i+2] == 0, return si (i +2) immediately without bothering
          to call extract_dollar_brace_string or extract_delimited_string
        - in skip_to_delim(), if string[i] is 0 after a call to
          extract_dollar_brace_string or extract_delimited_string (meaning we
          have an unclosed ${ or other expansion, return i immediately without
          doing a `continue' (which will increment i past the end of string)
        - in split_at_delims, don't increment te by 1 if it's pointing to a
          delimiter.  this has the effect of skipping the first delimiter
          char in a possibly multi-character delimiter, and ignoring
          single-char delimiters like `>'

configure.in
        - use AC_CHECK_MEMBERS([struct stat.st_blocks]) instead of a call to
          AC_STRUCT_ST_BLOCKS to avoid configure changing LIBOBJS if the test
          fails

general.c
        - introduce two new variables: bash_tilde_{prefixes,suffixes}, set
          to the additional prefixes and suffixes bash wants to pass to the
          tilde expansion code (reserved for post-bash-2.05a fix)

aclocal.m4

lib/readline/vi_mode.c

include/chartypes.h
        - remove superfluous `#undef ISASCII'

lib/sh/strto[iu]max.c
        - changes from Paul Eggert to work around buggy compilers and catch

aclocal.m4
        - new macro, BASH_C_LONG_DOUBLE, identical to AC_C_LONG_DOUBLE but
          with a fix for Irix 5.3 (not called, since I'm not sure it's the
          right thing to do -- the C standard allows double and long double
          to be the same size)

lib/sh/snprintf.c
