* Makefile.am (SUBDIRS): Remove intl.

* Makefile.am (SUBDIRS): Remove intl.
(DISTCLEANFILES): Remove.
* NEWS: Mention that GNU M4 is now required.  Clarify what is
meant by "larger grammars".  Mention the pt_BR translation.
* configure.in (AC_CHECK_DECLS): Add getenv, getopt.
(AM_GNU_GETTEXT_VERSION): New macro, replacing GETTEXT_VERSION var.
Bump version from 0.11.2 to 0.11.5.
(BISON_PREREQ_STAGE): Remove.
(AM_GNU_GETTEXT): Use external gettext.
(AC_OUTPUT): Remove intl/Makefile.

* config/depcomp, config/install-sh: Sync with Automake 1.6.3.

* data/glr.c: Include string.h, for strlen.
(yyreportParseError): Use size_t for yysize.
(yy_yypstack): No longer nested inside yypstates, as nested
functions are not portable.  Do not assume size_t is the
same width as int.
(yypstates): Do not assume that ptrdiff_t is the same width
as int, and similarly for yyposn and YYINDEX.

* data/yacc.c: Fix comment about `$$ = $1': it can copy garbage.

* lib/Makefile.am (INCLUDES): Do not include from the intl
directory, which has been removed.
* src/Makefile.am (INCLUDES): Likewise.

* lib/Makefile.am (libbison_a_SOURCES): Add unlocked-io.h.
(bitsets_sources, additional_bitsets_sources, timevars_sources):
New vars.

* lib/Makefile.am (libbison_a_SOURCES): Avoid +=, a GNU make extension.
* tests/Makefile.am (EXTRA_DIST): Likewise.

* lib/abitset.c (abitset_reverse_list, ebitset_reverse_list):
Do not assume that bitset_windex is the same width as unsigned.

* lib/abitset.c (abitset_unused_clear): Do not assume that
bitset_word is the same width as int.
* lib/bbitset.h (BITSET_INDEX_MAX, BITSET_MSB): Likewise.
* lib/bitset.h (bitset_set, bitset_reset): Likewise.
* lib/bitset_stats.c (bitset_stats_set, bitset_stats_reset): Likewise.
* lib/ebitset.c (ebitset_set, ebitset_reset): Likewise.
* lib/lbitset.c (lbitset_set, lbitset_reset): Likewise.

* lib/abitset.c (abitset_op1): Use -1, not ~0, as memset arg (for
portability to one's complement hosts!).
* lib/ebitset.c (ebitset_op1): Likewise.
* lib/lbitset.c (lbitset_op1): Likewise.

* lib/argmatch.c, lib/quotearg.c, quotearg.h: Sync with GNU tar.
* lib/argmatch.h, lib/basename.c, lib/dirname.c, lib/dirname.h,
lib/hash.c, lib/hash.h, lib/strnlen.c, lib/xmalloc.c:
Sync with fileutils.
* lib/error.c, lib/getopt.c, lib/getopt.h, lib/getopt1.c,
lib/gettext.h: Sync with diffutils.

* lib/memrchr.c, lib/mkstemp.c, lib/strchr.c, lib/strnlen.c,
lib/strspn.c, lib/tempname.c: Use GPL, not LGPL.

* lib/obstack.c, lib/obstack.h: Sync with fileutils, except use
PROTOTYPES to check for prototypes, and "defined __STDC__" to
check for void *.

* lib/bbitset.h (BITSET_WORD_BITS): Now of type unsigned, not
size_t; the old version tried to do this but casted improperly.
(bitset_bindex, bitset_windex): Now size_t, not unsigned long.
(bitset_test): Now returns int, not unsigned long.

* lib/bitset_stats.c: Include "gettext.h".
(_): New macro.
(bitset_stats_set, bitset_stats_reset, bitset_stats_test): Don't
name locals "index", as it generates unnecessary warnings on some
hosts that have an "index" function.

* lib/bitset_stats.c (bitset_stats_print_1, bitset_stats_print,
bitset_stats_read, bitset_stats_write): Wrap strings in _() if
they need translation.
* src/LR0.c (state_list_append, new_itemsets, get_state,
append_states, generate_states): Likewise.
* src/assoc.c (assoc_to_string): Likewise.
* src/closure.c (print_closure, set_firsts, closure): Likewise.
* src/gram.c (grammar_dump): Likewise.
* src/injections.c (injections_compute): Likewise.
* src/lalr.c (lookaheads_print): Likewise.
* src/relation.c (relation_transpose): Likewise.
* src/scan-gram.l: Likewise.
* src/tables.c (table_grow, pack_vector): Likewise.

* m4/Makefile.am (EXTRA_DIST): Remove codeset.m4,
glibc21.m4, isc-posix.m4 lcmessage.m4, stage.m4.
* m4/malloc.m4, m4/realloc.m4: Sync with diffutils.
* m4/mbstate_t.m4: Sync with fileutils.
* m4/prereq.m4 (jm_PREREQ_QUOTEARG): AC_MBSTATE_T -> AC_TYPE_MBSTATE_T.

* po/LINGUAS: Add pt_BR.
* po/POTFILES.in: Add src/assoc.c, src/closure.c, src/gram.c,
src/main.c, src/relation.c, src/state.c, lib/bitset_stats.c,
lib/timevar.c.
Use src/parse-gram.y instead of src/parse-gram.c, as the gettext
manual recommends.
Similarly, use src/scan-gram.l instead of src/scan-gram.c.

* src/complain.c (strerror_r): Remove decl; not needed.
(strerror): Use same pattern as ../lib/error.c.

* src/files.c, src/files.h (compute_header_macro): Remove; unused.

* src/gram.c (grammar_dump): Do not assume ptrdiff_t fits in int.

* src/main.c (main): Cast result of bindtextdomain and textdomain
to void, to avoid a GCC warning when --disable-nls is in effect.

* src/scan-gram.l: Use strings rather than escapes when possible,
to minimize the number of warnings from xgettext.
(handle_action_dollar, handle_action_at): Don't use isdigit,
as it mishandles negative chars and it may not work as expected
outside the C locale.

* src/symtab.c (symbol_get): Don't cast LHS of an assignment;
this is a GCC extension and is not portable to other compilers.

* src/system.h (alloca): Use same pattern as ../lib/error.c.
Do not include <ctype.h>; no longer needed.
Do not include <malloc.h>; no longer needed (and generates
warnings on OpenBSD 3.0).

* tests/cxx-type.at (yylex): Do not pass signed char to isupper;
it's not portable.

* tests/regression.at: Do not use 'cc -c input.c -o input';
Sun C rejects this.  Instead, use 'cc -c input.c -o input.o'.

* tests/synclines.at (AC_SYNCLINES_COMPILE): Accept any nonzero
exit status as failure, not just exit status 1.  Sun C exits
with status 2 sometimes.

* tests/torture.at (AT_INCREASE_DATA_SIZE): New macro.
Use it for the two large tests.
