Of all the installed programs (autoconf, autoheader, autom4te,
autoreconf, autoscan, autoupdate, ifnames) autoconf is the only one
that is a shell script instead of a Perl script. This means it has to
do a lot of fiddly quoting and requoting to assemble an autom4te
command line, it doesn’t get to use the shared option handling code in
Autom4te/{General,Getopt}.pm, and it has to duplicate usage text that
properly should only be in Autom4te/ChannelDefs.pm. It also means
there’s extra code in build-aux/help-extract.pl just for it, and a
special two-phase generation process in bin/local.mk.
This also paves the way for the bootstrap script mentioned in the
previous commit; it will only have to know how to deal with
substitution variables, not generation of m4sh scripts.
The new script winds up being slightly longer on disk but that’s
because our boilerplate for Perl scripts is quite long. The code is
visibly simpler.
* bin/autoconf.as: Rename to bin/autoconf.in and rewrite in Perl.
* bin/local.mk (EXTRA_DIST): Change autoconf.as to autoconf.in.
(MOSTLYCLEANFILES): Don’t delete autoconf.in.
(bin/autoconf.in): Delete rule.
(ETAGS_PERL): Add autoconf.in and sort list.
(ETAGS_SH): Delete, no longer needed.
* tests/tools.at: Syntax-check autoconf as a Perl script.
* build-aux/help-extract.pl: Remove all code for extracting usage text
from shell scripts.
* man/autoconf.w, man/local.mk: Refer to autoconf.in, not autoconf.as.
As pointed out in sr #110368, since install-sh is now being installed
as part of autoconf, we should make sure to ship the latest version
rather than the version shipped by the automake that was used to
bootstrap the autoconf release tarball.
The build-aux/fetch.pl script is already supposed to fetch the latest
version, but install-sh is listed in .gitignore so any updates are
discarded when starting from a clean tree. Correct this.
At the same time, since mdate-sh is *not* installed by autoconf nor is
it directly referenced in any code maintained in the autoconf
repository, remove it from the list of files to fetch and keep it in
.gitignore.
This change exposed a bug in fetch.pl where it would crash when
there was no old copy of a file being updated.
* .gitignore: Remove /build-aux/install-sh.
* build-aux/fetch.pl (%to_fetch): Remove build-aux/mdate-sh.
(slurp): Don’t die on ENOENT, return undef.
(replace_if_change): Handle $oldcontents being undef.
* build-aux/install-sh: Is now checked in.
* .gitignore: Here.
* Makefile.am (check-coverage-run): Use $(MKDIR_P) rather than
$(mkinstalldirs).

* .gitignore: Adjust.
* Makefile.am ($(srcdir)/doc/local.mk): New include.
(SUBDIRS): Drop 'doc'.
(AM_MAKEINFOFLAGS): Rename ...
(custom_MAKEINFOFLAGS): ... like this, to avoid conflicting with
the AM_MAKEINFOFLAGS defined in the included 'doc/local.mk'
($(srcdir)/INSTALL): Adjust recipe.
* doc/Makefile.am: Rename ...
* doc/local.mk: ... like this, and adjust.
* configure.ac (AC_CONFIG_FILES): Drop 'doc/Makefile'.

Following the practice set by various other GNU projects, we start
to automatically generate the ChangeLog file from the git commit
messages. This will avoid duplication (as the ChangeLog entries
were always inserted both in the git commit message and in the
version-controlled ChangeLog file), and potential problems with
spurious merge conflicts (which, although greatly mitigated by
Bruno Haible's `git-merge-changelog' helper program, have never
been completely solved).
* ChangeLog: Moved ...
* ChangeLog.3: ... to this.
* build-aux/gitlog-to-changelog: New script, synced from gnulib.
* cfg.mk (gnulib-update): Also sync gitlog-to-changelog.
* Makefile.am (gen-ChangeLog): New .PHONY rule, generate the
ChangeLog for distribution.
(dist-hook): Depend on it.
($(srcdir)/ChangeLog): New dummy rule, to pacify automake "gnu"
strictness. Creates a dummy ChangeLog, that will be overridden
by the proper one at distribution time.
(gen_start_date): New variable, the date starting from which the
git log entries are to be copied in the generated ChangeLog.
(EXTRA_DIST): Add ChangeLog.3 and gitlog-to-changelog.
* configure.ac (AC_CONFIG_SRCDIR): Use 'lib/autoconf/autoconf.m4'
instead of 'ChangeLog' as the sentinel file.
* .gitignore: Add ChangeLog.
Now, each unofficial build has a version "number" like 2.61a-19-58dd,
which indicates that it is built using the 19th change set
(in _some_ repository) following the "v2.61a" tag, and that 58dd
is a prefix of the commit SHA1.
* build-aux/git-version-gen: New file.
* configure.ac: Run it to set the version.
(AM_INIT_AUTOMAKE): Don't check NEWS here.
* Makefile.am (dist-hook): Arrange so that .version appears only
in distribution tarballs, never in a checked-out repository.
* .gitignore: Add .version here, too. Just in case.
* tests/Makefile.am ($(srcdir)/package.m4): Depend on Makefile,
not configure.ac, now that the version number changes automatically.
Ensure that $(VERSION) is up to date for dist-related targets.
* GNUmakefile: Arrange to rerun autoconf, if the version reported by
git-version-gen doesn't match $(VERSION), but only for dist targets.
* aclocal.m4: Remove.
* configure: Remove.
* Makefile.in: Remove, along with all other Makefile.in in subdirs.
* .gitignore: Add aclocal.m4, configure and Makefile.in. Sort.
* README-hacking: New file: how to build from just-checked-out sources.
