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.
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/autoconf.in, bin/autoheader.in, bin/autoreconf.in,
* bin/autoscan.in, autoupdate.in: Use exclusively the name of the
installed peer executables, only PATH is allowed to resolve it.
Pass `autoconf_dir' via options, not via invisible envvars.
* lib/Autom4te/General.pm (&find_peer): Remove.
* lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
`abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
* man/Makefile.am: Let help2man rely on PATH instead of trying to
find the executables for it.
* tests/Makefile.am: Major cleanup. Too lazy to document...
* tests/atlocal.in: Remove all the obscure envvar manipulations.
We only need PERL.
* tests/atspecific.m4, tests/tools.at: Passing --localdir is
indeed related to running the test suite, while passing
--autoconf-dir and others is related to running non installed
Autoconf executables. So don't do that, leave it to...
* tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
* tests/autoscan: New.
* tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't
refer to library files: rely on --language.
top_srcdir and srcdir from at_topbuild_2_topsrc and at_testdir.
Load atlocal late enough to dump it in the log.
* m4/atconfig.m4 (AT_CONFIG): Pass them to atconfig.
* m4/atconfig.m4 (AT_CONFIG): $1 is now the directory where the
test suite lives.
Create `atconfig' automagically.
Configure atlocal.in if present.
* tests/atconfig.in: Remove.
* tests/atlocal.in: New.
* tests/Makefile.am: Adjust.
* test/tools.at: Use AT_CHECK_AUTOCONF.
(AWK portability): Remove, for autoconf no longer uses AWK.
(Syntax of the Perl scripts): New.
* configure.ac: autoconf no longer needs an AWK with a good
regexp engine.
Use a static test on AC_PACKAGE_VERSION.
* autom4te.in (&up_to_date_p): Output depends on the arguments.
* lib/autoconf/Makefile.am: Ship version.m4, maintainer file.
* tests/atconfig.in (PERL): New.
