ac_buildpath, ac_top_buildpath, ac_srcpath, and ac_top_srcpath.
(_AC_OUTPUT_FILES): Also substitute srcpath, top_srcpath,
builddir, buildpath, top_builddir, and top_buildpath.
(_AC_OUTPUT_SUBDIRS): Compute the dir variables *before* changing
the current directory.
* lib/autoconf/general.m4 (_AC_INIT_HELP): Compute the dir
variables *before* changing the current directory.
Skip nonexistent dirs.
* doc/autoconf.texi (Preset Output Variables): Document these
variables.
* lib/autotest/general.m4: Do not reset AT_victims.
Don't compute at_srcdir nor at_top_srcdir.
* tests/tools.at: Hence use top_srcdir.
* tests/Makefile.am, tests/autoconf, tests/autoheader,
* tests/autom4te, tests/autoreconf, tests/autoupdate, tests/ifnames:
Remove.
* tests/autoreconf.in, tests/wrappl.in, tests/autom4te.in,
* tests/wrapsh.in, tests/autoupdate.in: New.
* tests/Makefile.am (DISTCLEANFILES, EXTRA_DIST): Adjust.
* configure.ac: Build the position independent wrappers.
* man/Makefile.am: Now that test wrappers are position
independent, use them and drop dark envvar magic.
* bin/autom4te.in (&find_file): Support `FILE?' standing for
optionally `FILE'.
Use -e, not -f, since /dev/null for instance is OK.
(&parse_args): Adjust.
* lib/autom4te.in (Autoconf): Add `acsite.m4?' and `aclocal.m4?'.
* lib/Makefile.am (edit, autom4te.cfg): New.
* bin/autom4te.in (BEGIN): Simplify.
Rely on `AC_MACRODIR' in addition of `autom4te_perllibdir'.
(&load_configuration): New. Use it.
(&parse_args): Support --mode, --set, and --melt.
* bin/autoconf.in: Simplify and adjust.
* tests/Makefile.am (AUTOMAKE): Use --set.
* tests/atlocal.in: Adjust.
* BUGS: distcheck and check are weak.
* Makefile.am (AUTOMAKE_OPTIONS): Add 1.5 and dist-bzip2.
(AMTAR): Help automake define it.
(INSTALL, install-data-hook): The INSTALL.txt trick is no longer
needed, 1.5 can have a macro and a target with the same name.
* m4/auxdir.m4, m4/cond.m4, m4/depend.m4, m4/install-sh.m4,
* m4/strip.m4: New.
* m4/init.m4, m4/sanity.m4: Update.
* doc/Makefile.am (CLEANFILES): 1.5 knows the texi2dvi files.
* lib/autoconf/Makefile.am, lib/autotest/Makefile.am,
* lib/m4sugar/Makefile.am, lib/autoscan/Makefile.am,
* lib/Autom4te/Makefile.am, man/Makefile.am: Use dist/nodist.
`0'. Test and fix.
Reported by Assar Westerlund.
* Makefile.am (maintainer-check): New target.
* tests/Makefile.am (maintainer-check, maintainer-check-posix)
(maintainer-check-c++, expr): Likewise.
* configure.in (EXPR): Look for it.
* tests/atgeneral.m4 (AT_CHECK): Propagate $2's default value.
* tests/compile.at (Extensions): New test.
* aclang.m4 (_AC_COMPILER_EXEEXT_DEFAULT, _AC_COMPILER_EXEEXT_O):
Distinguish files with or without a dot.
2.5.1 only the last one is honored:
> echo "foonbar" | egrep -e 'foo' -e 'bar'
bar
> echo "foonbar" | egrep -e 'bar' -e 'foo'
foo
Reported by Nicolas Joly.
An alternative would have to use `sed', unfortunately alternation
is not portable.
* tests/actest.m4 (join): New macro.
(AC_ENV_SAVE): Join the egrep patterns into a single big one.
* tests/Makefile.am (EGREP_EXCLUDE): Rename as FILTER_MACROS.
Join the egrep patterns into a single big one.
* acgeneral.m4 (AC_CHECK_MEMBER): It is not smart to define
ac_Foo, and use AC_Foo. Got rid of AC_Member_Aggregate and
AC_Member_Member which were complicating more than simplifying.
(AC_CHECK_DECLS): Use m4 lists.
(AC_CHECK_TYPES): A comma was missing.
* autoheader.m4: (AC_CHECK_DECLS): Use m4 lists.
* doc/autoconf.texi (Generic Declarations): AC_CHECK_DELCS uses m4
lists.
* tests/semantics.m4: New file. Collection of semantical tests:
verify that the tests are positive and negative when appropriate.
Test AC_CHECK_MEMBERS, AC_CHECK_DECLS and AC_CHECK_TYPES.
Introduce a new style of testing, independent from DejaGNU.
Introduce the logistics.
* configure.in: Initialize AT, and output tests/atconfig, and
tests/Makefile.

* m4/Makefile.am: Adjusted.
* aclocal.m4: Include atconfig.m4.
* Makefile.am: Adjusted.
* tests/Makefile.am: New file.
* tests/atgeneral.m4: Likewise.
* tests/atconfig.in: Likewise.
Write tests.
* tests/syntax.m4: New file, in charge of checking the validity of
the sh code produced by the macros defined in acspecific.m4.
acgeneral.m4 is not checked here, because these macros require
arguments.
* tests/suite.m4: New file. Run syntax.m4.
New version of AC_INCLUDE, which does not glob, nor rely upon the
shell. Add AC_INCLUDES too. Help tracking multiple inclusions.
* acgeneral.m4 (m4_errprint, m4_warn, m4_fatal): New macros,
variations around errprint.
(m4_include_unique): New macro which registers what are the files
already included, and warns if some are included several times.
(m4_include, m4_sinclude): New macro, using m4_include_unique.
(AC_INCLUDE): Is now just a wrapper of m4_include.
(AC_INIT): Use m4_sinclude, not sinclude.
(_AC_ERRPRINT): Removed, m4_errprint is here!
(AC_WARNING, AC_FATAL): Wrappers of m4_warn and m4_fatal.
Create man pages for the executables.
* Makefile.am (SUBDIRS): Add `man' and prepend `.' so that
executables be built before help2man is run.

AC_MSG_ERROR, not AC_ERROR.
Check for missing help2man.
