Major changes in release 1.8:
* AC_PROG_INSTALL uses install.sh instead of cp if it's found.
* AC_OUTPUT adds its comments in C format when substituting in C files.
Major changes in release 1.7:
* New macro AC_OBSOLETE.
* Bugs in Makefile.in fixed.
* AC_LONG_FILE_NAMES improved.
Major changes in release 1.6:
* New macro AC_LONG_64_BITS.
* Multiple .h files can be created.
* AC_FIND_X looks for X files directly if it doesn't find xmkmf.
* AC_ALLOCA defines C_ALLOCA if using alloca.c.
* --with-NAME can take a value, e.g., --with-targets=sun4,hp300bsd.
* Unused --no-create option to configure removed.
* autoheader doesn't change the timestamp of its output file if
the file didn't change.
* All macros that look for libraries now use AC_HAVE_LIBRARY.
* config.status checks three optional environment variables to
modify its behavior.
* The usual bug fixes.
Major changes in release 1.5:
* New macros AC_FIND_X, AC_OFF_T, AC_STAT_MACROS_BROKEN, AC_REVISION.
* autoconf and autoheader scripts have GNU standards conforming
--version and --help options (they print their message and exit).
* Many bug fixes.
Major changes in release 1.4:
* New macros AC_HAVE_POUNDBANG, AC_TIME_WITH_SYS_TIME, AC_LONG_DOUBLE,
AC_GETGROUPS_T, AC_DEFINE_UNQUOTED.
* autoconf and autoheader use the M4 environment variable to determine the
path of the m4 program to use.
* The --macrodir option to autoconf and autoheader specifies the directory
in which acspecific.m4, acgeneral.m4, etc. reside if not the default.
* autoconf and autoheader can take `-' as their file names, which means to
read stdin as input.
* Resulting configure scripts can take a --verbose option which causes them
to print the results of their tests.
* AC_DEFINE quotes its second argument in such a way that spaces, magic
shell characters, etc. will be preserved during various stages of
expansion done by the shell. If you don't want this, use
AC_DEFINE_UNQUOTED instead.
* Much textual processing done with external calls to tr and sed have been
internalized with builtin m4 `patsubst' and `translit' calls.
* AC_OUTPUT doesn't hardwire the filenames it outputs. Instead, you can
set the shell variables `gen_files' and `gen_config' to the list of
filenames to output.
* AC_DECLARE_YYTEXT does an AC_SUBST of `LEX_OUTPUT_ROOT', which may be
"lex.yy" or "lexyy", depending on the system.
* AC_PROGRAMS_CHECK takes an optional third arg. If given, it is used as
the default value.
* If AC_ALLOCA chooses alloca.c, it also defines STACK_DIRECTION.
* AC_CONST works much more reliably on more systems.
* Many bug fixes.
Major changes in release 1.3:
configure no longer requires awk for packages that use a config.h.
Support handling --with-PACKAGE options.
New `autoheader' script to create `config.h.in' from `configure.in'.
Ignore troublesome -lucb and -lPW when searching for alloca.
Rename --exec_prefix to --exec-prefix for GNU standards conformance.
Improve detection of STDC library.
Add AC_HAVE_LIBRARY to check for non-default libraries.
Function checking should work with future GNU libc releases.
Major changes in release 1.2:
The --srcdir option is now usually unnecessary.
Add a file containing sample comments describing CPP macros.
A comment in config.status tells which host it was configured on.
Substituted variable values can now contain commas.
Fix bugs in various feature checks.
Major changes in release 1.1:
Added AC_STRCOLL macro.
Made AC_GETLOADAVG check for more things.
AC_OUTPUT argument is now optional.
Various bug fixes.
