2 * Autoconf 2.54 is required.
3 * `aclocal' and `automake' will no longer warn about obsolete
4 configure macros. This is done by `autoconf -Wobsolete'.
5 * AM_CONFIG_HEADER, AM_SYS_POSIX_TERMIOS and
6 AM_HEADER_TIOCGWINSZ_NEEDS_SYS_IOCTL are obsolete (although still
7 supported). You should use AC_CONFIG_HEADERS, AC_SYS_POSIX_TERMIOS,
8 and AC_HEADER_TIOCGWINSZ instead. `autoupdate' can upgrade
9 `configure.ac' for you.
10 * Support for per-program and per-library `_CPPFLAGS'.
11 * New `ctags' target (builds CTAGS files).
12 * Support for -Wmumble and -Wno-mumble, where mumble is a warning category
13 (see `automake --help' or the manual for a list of them).
14 * Honor the WARNINGS environment variable.
15 * Omit the call to depcomp when using gcc3: call the compiler directly.
16 * A new option, std-options, tests that programs support --help and --version
17 when `make installcheck' is run. This is enabled by --gnits.
18 * Texinfo rules now support the `ps' and `pdf' targets.
19 * Info files are now created in the build directory, not the source directory.
20 * info_TEXINFOS supports files in subdirectories (this requires Texinfo 4.1
22 * `make distcheck' will enforce DESTDIR support by attempting
24 * `+=' can be used in conditionals, even if the augmented variable
25 was defined for another condition.
26 * Makefile fragments (inserted with `include') are always distributed.
27 * Use Autoconf's --trace interface to inspect configure.ac and get
28 a more accurate view of it.
29 * Add support for extending aclocal's default macro search path
30 using a `dirlist' file within the aclocal directory.
31 * automake --output-dir is deprecated.
32 * The part of the distcheck target that checks whether uninstall actually
33 removes all installed files has been moved in a separate target,
34 distuninstallcheck, so it can be overridden easily.

39 * automake no longer run libtoolize.
40 This is the job of autoreconf (from GNU Autoconf).
41 * `dist' generates all the archive flavors, as did `dist-all'.
42 * `dist-gzip' generates the Gzip tar file only.
43 * Combining Automake Makefile conditionals no longer lead to a combinatorial
44 explosion. Makefile.in's keep a reasonable size.
45 * AM_FUNC_ERROR_AT_LINE, AM_FUNC_STRTOD, AM_FUNC_OBSTACK, AM_PTRDIFF_T
46 are no longer shipped, since Autoconf 2.52 provides them (both as AM_
48 * `#line' of Lex and Yacc files are properly set.
49 * EXTRA_DIST can contain generated directories.
50 * Support for dot-less extensions in suffix rules.
51 * The part of the distcheck target that checks whether distclean actually
52 cleans all built files has been moved in a separate target, distcleancheck,
53 so it can be overridden easily.
54 * `make distcheck' will pass additional options defined in
55 $(DISTCHECK_CONFIGURE_FLAGS) to configure.
56 * Fixed CDPATH portability problems, in particular for MacOS X.
57 * Fixed handling of nobase_ targets.
58 * Fixed support of implicit rules leading to .lo objects.
59 * Fixed late inclusion of --add-missing files (e.g. depcomp) in DIST_COMMON
60 * Added uninstall-hook target
61 * `AC_INIT AM_INIT_AUTOMAKE(tarname,version)' is an obsolete construct.
62 You can now use `AC_INIT(pkgname,version) AM_INIT_AUTOMAKE' instead.
63 (Note that "pkgname" is not "tarname", see the manual for details.)
64 It is also possible to pass a list of global Automake options as
65 first argument to this new form of AM_INIT_AUTOMAKE.
66 * Compiler-based assembler is now called `CCAS'; people expected `AS'
67 to be a real assembler.
68 * AM_INIT_AUTOMAKE will set STRIP itself when it needs it. Adding
69 AC_CHECK_TOOL([STRIP], [strip]) manually is no longer required.
70 * aclocal and automake are also installed with the version number
71 appended, and some of the install directory names have changed.
72 This lets you have multiple versions installed simultaneously.
73 * Support for parsers and lexers in subdirectories.
76 * Support for `configure.ac'.
77 * Support for `else COND', `endif COND' and negated conditions `!COND'.
78 * `make dist-all' is much faster.

97 e.g. AM_CFLAGS can be used in Makefile.am to set C compiler flags
98 * Support for latest autoconf, including support for objext
99 * Can now put `.' in SUBDIRS to control build order
100 * `include' command and `+=' support for macro assignment
101 * Dependency tracking no long susceptible to deleted header file problem

107 * Better Cygwin32 support
108 * Support for suffix rules with _SOURCES variables
