Fixes the `AC_ARG_VAR' test failures.
* lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Don't use cmp.
* lib/freeze.mk (check-forbidden-patterns): New.
* lib/autoconf/Makefile.am, lib/autotest/Makefile.am
* lib/m4sugar/Makefile.am (check-local): Use it to catch `cmp'.
* doc/autoconf.texi (Limitations of Usual Tools): HP-UX' cmp and
/dev/null.
Reported months ago by H. Merijn Brand.
autoheader are Perl programs.
(autoconf, autoheader, autoreconf, autoupdate, ifnames, autoscan)
(autom4te): Specify that the sources are in the $srcdir.
* doc/autoconf.texi (Installation Directory Variables): Adjust.
* lib/autoconf/autoconf.m4: Include it.
* lib/autoconf/functions.m4: Use AN_FUNCTION for all the functions
that were listed in the original autoscan.list.
* lib/autoconf/headers.m4: Similarly with headers.
* lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
(.m4.m4f): Don't pass --prepend-include, since that's done by
tests/autom4te itself.
* lib/autoscan/Makefile.am: Include freeze.mk.
(autoscan.list): New target --this file is no longer a source.
(autoscan.pre): New file.
Adjust all uses.
(&init_tables): When --debug, report the list of rules to ease
tracking changes in autoscan.list.
* lib/autoscan/autoscan.list (function): Strip comments, sort.
* lib/autoscan/identifiers, lib/autoscan/makevars,
* lib/autoscan/programs: Make the `kind' explicit, i.e., each
`functions' line is now prefixed with `function:'.
* bin/autoscan.in (&init_tables): Adjust.
word: there is no `default' macro for autoscan.
* bin/autoscan.in (&init_tables): Reject entries with no macro at
all.
* lib/autoscan/functions, lib/autoscan/headers: Make the macro
explicit.
Remove, replaced by...
* tests/wrappl.in: Be common for all the Perl executables.
In particular autoscan and autoheader want -I.
* configure.ac: Adjust.
* lib/autoscan/headers: errno.h is portable.
directives.
(&scan_sh_file): Remove a duplicate pattern.
(&check_configure_ac): Use long options.
* lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.
* 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.
(&init_tables): Die when a word which is already handled by
explicit macros is mapped to the default macro.
(&print_unique): Remove, inlined in...
(&output_kind): here.
(File::Basename): Use it.
(&output): Sort the CONFIG_FILES.
* acheaders: Normalize.
* acfunctions: Likewise.
(_AC_FUNC_VFORK): this.
Remove AC_DEFINEs and don't guess cross-compilation values.
(_AC_FUNC_FORK): New, check whether fork() isn't just a stub.
(AC_FUNC_FORK): New, use _AC_FUNC_VFORK and _AC_FUNC_FORK to
define HAVE_WORKING_FORK, HAVE_WORKING_VFORK; and vfork to fork if
vfork doesn't work.
Guess values if cross-compiling, but warn.
* acfunctions: Add AC_FUNC_FORK.
* doc/autoconf.texi: Document AC_FUNC_FORK. Give example to define
and vfork appropriately.
(&init_tables): Use them.
* acheaders: Run `autoconf -t AC_CHECK_HEADERS:'$1'' on the fileutils,
and include all these headers in here.
Don't specify `AC_CHECK_HEADERS' as it's the default.
in autoscan tables. Die if there are no spaces at all.
(scan_c_file): Use b instead of W so that keywords match at
the beginning and the end of the line.
(scan_sh_file): Likewise.
(scan_makefile): Likewise. Use B to match before `-l'.
(output): Suggest AC_CONFIG_HEADER if any C/C++ sources are
found.
* acidentifiers: Update macros for structure members st_blksize
and st_rdev.
