	partially reverting the change of 26 Apr 2012 for bug#11347.
	Otherwise, new tests that have dependencies will not cause an
	update of testsuite-part.am, leading to strange failures
	(bug#44458). The original problem being fixed in #11347 was
	unnecessary rebuilding when modifying tests; that should not be
	affected here, but when new tests are added, it seems reasonable,
	as well as necessary, to ensure dependencies are updated.

	Use complete configure.ac’s in testsuite.

	Autoconf 2.70 will issue warnings if it encounters a configure.ac that doesn’t
	call both AC_INIT and AC_OUTPUT.

	Automake already issues warnings if it encounters a configure.ac that uses an
	AM_ macro but doesn’t call AM_INIT_AUTOMAKE or AC_CONFIG_FILES([Makefile]).

	In two places, the testsuite was tripping these warnings, leading to spurious
	failures with Autoconf 2.70 betas.

	* t/aminit-moreargs-deprecation.sh: Add AC_OUTPUT to test configure.ac.
	* t/mkdirp-deprecation.sh: Use a complete test configure.ac, not a stub

	Update documentation of warnings options and strictness levels.

	The warning categories ‘cross’ and ‘portability-recursive’ were not mentioned
	in the manual.

	Also clarify the relationship between warnings categories and strictness
	levels, and streamline the description of strictness levels by merging the
	“Gnits” section into the “Strictness” section.

	* doc/automake.texi (Gnits, Strictness): Combine these sections.
	  Minor revisions to explanation of strictness levels.
	  (automake Invocation): Add documentation of all the warnings
	  categories that have been added since the last time this section
	  was updated.  Minor clarifications.

2020-09-21  Zack Weinberg  <zackw@panix.com>

	Use WARNINGS=none to suppress warnings from autom4te runs.

	aclocal uses autom4te in trace mode to scan configure.ac for macros whose
	definition is not yet available.  It has a kludge to prevent this from
	producing spurious warnings, but a cleaner, fully backward compatible, way to
	get the same effect is to set WARNINGS=none in the environment and not pass
	down any -W options.  (This is better than passing -Wnone on the command line
	because it automatically inherits to any subprocesses started by autom4te.)

	Perl’s ‘local’ feature can be used to make the enviironment variable setting
	temporary, reverting to the previous value when we exit the function.

	automake also runs autom4te (technically autoconf) in trace mode; warnings
	from this invocation will not be *spurious*, but in the common case where
	the person running automake is going to run autoconf next, they will be
	duplicated.  Therefore, make the same change to automake.

	* bin/aclocal.in (trace_used_macros)
	* bin/automake.in (scan_autoconf_traces):
	  Use “local $ENV{WARNINGS}='none'” to suppress warnings from autom4te.

2020-09-18  Zack Weinberg  <zackw@panix.com>

	New utility function Automake::ChannelDefs::merge_WARNINGS.

	This function merges a list of warnings categories into the environment
	variable WARNINGS, returning a new value to set it to.  The intended use
	is in code of the form

	{
	  local $ENV{WARNINGS} = merge_WARNINGS ("this", "that");

	  # run a command here with WARNINGS=this,that,etc
	}

	This is not actually used in automake, but will be in autoconf.

	* lib/Automake/ChannelDefs.pm (merge_WARNINGS): New function.

2020-09-12  Zack Weinberg  <zackw@panix.com>

	t/python-virtualenv.sh: Skip when versions don’t match

	On some operating systems ‘python’ is Python 2.x but ‘virtualenv -ppython’
	will create a virtualenv that uses Python 3.x.  This is a bug, but it’s
	not *automake’s* bug, and should not cause t/python-virtualenv.sh to fail.
	Skip the test, instead of failing it, when the inner=outer version check
	fails.

	(This also has nothing to do with the main goal of this patchset, it just
	annoyed me while I was testing.)

	* t/python-virtualenv.sh: Skip test, rather than failing it, when
	  $py_version_pre != $py_version_post.

2020-09-12  Zack Weinberg  <zackw@panix.com>

	Consistently use ‘our’ instead of ‘use vars’.

	At file scope of a file containing at most one ‘package’ declaration,
	‘use vars’ is exactly equivalent to ‘our’, and the latter is preferred
	starting with Perl 5.6.0, which happens to be the oldest version we
	support.

	(This change has nothing to do with the previous two, but I want to make the
	same change in Autoconf and that means doing it here for all the files synced
	from Automake.)

	(I don’t know why, but this change exposed a latent bug in FileUtils.pm where
	the last pod block in the file didn’t have a ‘=cut’ delimiter, so the code
	after it was considered documentation, causing ‘require FileUtils’ to fail.)

2020-09-12  Zack Weinberg  <zackw@panix.com>

	Consistently process -W(no-)error after all other warning options.

	automake and aclocal were processing ‘-W(no-)error’ whenever it
	appeared on the command line, which means that
	‘-Werror,something-strange’ would issue a hard error, but
	‘-Wsomething-strange,error’ would only issue a warning.

	It is not desirable for warnings about unknown warning categories ever to be
	treated as a hard error; that leads to problems for driver scripts like
	autoreconf, which would like to pass whatever -W options it got on its own
	command line down to all the tools and not worry about which tools understand
	which warning categories.  Also, this sort of order dependence is confusing
	for humans.

	Change parse_warnings to take just one option, the _complete_ list of warning
	categories seen on the command line, and to process -Werror / -Wno-error after
	processing all other warnings options.  Thus, unknown warnings categories will
	always just be a plain warning.  This does mean aclocal has to stop using
	parse_warnings as a Getopt::Long callback, but that’s not a big deal.

	Similarly, change parse_WARNINGS to record whether ‘error’ appeared in the
	environment variable, but not activate warnings-are-errors mode itself.
	parse_warnings picks up the record and honors it, unless it’s overridden by
	the command line.

	* lib/Automake/ChannelDefs.pm ($werror): New package global (not exported).
	  (parse_WARNINGS): Do not call switch_warning for ‘error’ / ‘no-error’;
	  just toggle the value of $werror.
	  (parse_warnings): Do not call switch_warning immediately for
	  ‘error’ / ‘no-error’; toggle $werror instead.  Call switch_warning ‘error’
	  at the very end if $werror is true.  Remove unused $OPTION argument.
	* bin/automake.in: parse_warnings now takes only one argument.
	* bin/aclocal.in: Call parse_warnings after parse_options instead of
	  using it as a parse_options callback.

2020-09-11  Zack Weinberg  <zackw@panix.com>

	Sync ChannelDefs.pm from autoconf.

	ChannelDefs.pm *ought* to be kept in sync between automake and autoconf,
	because it defines the set of valid -W options, and autoreconf assumes
	that it can pass arbitrary -W options to all of the tools it invokes.
	However, it isn’t covered by either project’s ‘make fetch’ and it hasn’t
	actually *been* in sync for more than 17 years.

	This patch manually brings over all of the changes made on the autoconf side.
	Most importantly, there is a new warnings channel ‘cross’, for warnings
	related to cross-compilation.  Also, the ‘usage’ function now *returns*
	the text to be put into a usage message, instead of printing it itself.
	(This is necessary on autoconf’s side.)

	* lib/Automake/ChannelDefs.pm: Sync from autoconf.
	  (cross): New warnings channel.
	  (portability-recursive): Document.
	  (usage): Now returns the text to be printed, instead of printing it.
	  (parse_warnings): Second argument may now be a list.

2020-05-25  Karl Berry  <karl@freefriends.org>

	docs: forgot TAR in NEWS; fix " -- " in manual.

	* NEWS: it seems the TAR envvar was never mentioned in NEWS;
	add it, back for 1.11.3 when it was apparently implemented.
	* doc/automake.texi: consistently use "---" instead of " --".

2020-05-25  Karl Berry  <karl@freefriends.org>

	docs: TAR envvar overrides "tar" for make dist.

	This change finishes https://bugs.gnu.org/9822.

	* doc/automake.texi (Basics of Distribution): mention that
	environment variable TAR overrides "tar".

2020-05-17  Karl Berry  <karl@freefriends.org>

	automake: new variable AM_DISTCHECK_DVI_TARGET to override "dvi".

	This change fixes https://bugs.gnu.org/8289.

	* lib/am/distdir.am (AM_DISTCHECK_DVI_TARGET): define as dvi.
	(distcheck): use it, isntead of hardcoding dvi.
	* lib/Automake/Variable.pm (%_silent_variable_override): add
	AM_DISTCHECK_DVI_TARGET.
	* t/distcheck-override-dvi.sh: new test.

	Various other index entries and wording tweaks.
	* NEWS (Distribution): mention this.

2020-05-10  Karl Berry  <karl@freefriends.org>

	automake: remove unused Automake::FileUtils::up_to_date_p function.

	Per thread at:
	https://lists.gnu.org/archive/html/automake-patches/2020-04/msg00000.html>
	especially:
	https://lists.gnu.org/archive/html/automake-patches/2020-05/msg00003.html

	* lib/Automake/FileUtils.pm (up_to_date_p): remove.
	Nothing in Automake itself uses this.  It is used in Autoconf's
	autom4te utility, but Autoconf has its own copy, and the duplication
	was impeding auto4mte development, as discussed in the thread above.
	(While here, insert missing =over/=back to placate pod2text.)
	* NEWS (Miscellanous changes): note this.

2020-05-07  Karl Berry  <karl@freefriends.org>

	docs: make dist implies make dvi.

	This change handles https://bugs.gnu.org/7994.

	* doc/automake.texi (Preparing Distributions): make distcheck
	runs make dvi.
	(Auxiliary Programs) <texinfo.tex>: mention
	that make dist runs make dvi, and therefore a TeX system is
	required when Texinfo sources are present. Add @cmindex entries
	for all auxiliary programs while we're here.

2020-05-07  Karl Berry  <karl@freefriends.org>

	tests: TeX system required for two more tests.

	* t/instdir-no-empty.sh (required): makeinfo tex texi2dvi dvips.

	I think that it is sufficient to fix the example (the explanation
	is just below). BTW, the second example is also incorrect.

	* lib/am/python.am (uninstall-%DIR%PYTHON): Uninstall
	byte-compiled files in a '__pycache__' subdirectory

	https://lists.gnu.org/archive/html/automake-patches/2018-05/msg00000.html
	* t/instmany-python.sh (limit): increase to 4500, following
	Andreas Huettel, https://debbugs.gnu.org/32088#11.

2020-01-29  Lukas Fleischer  <lfleischer@lfos.de>

	tests: in python tests, do not require .pyo files (for python3)

	This change partially fixes automake bug#32088:
	https://debbugs.gnu.org/32088

	* t/py-compile-basedir.sh: Remove all .pyo checks.
	Also, in this test only, allow for either 4 or 6 files resulting
	from compilation, as new-enough Python3 results in 6
	(per Andreas Huettel, https://debbugs.gnu.org/cgi/bugreport.cgi?bug=32088#17)
	* t/py-compile-basic.sh: Remove all .pyo checks.

	* maintainer/syntax-checks.mk (syntax-check): new target,
	same as maintainer-check. For consistency with many other
	GNU packages.
	(.PHONY): add here too.

2020-01-19  Karl Berry  <karl@freefriends.org>

	tests: use find+rm, not perl, to remove temporary directories.

	This change fixes automake bug#39078:
	https://debbugs.gnu.org/39078

	* t/ax/test-lib.sh (rm_rf_): run chmod -R u+rwx and rm -rf,
	instead of calling our t/ax/deltree.pl script.  This reverses the
	change of 2013-05-16.  It made sense to write and use deltree
	at that point, but unfortunately as of perl-5.28.0
	(File::Path.pm version 2.15), rmtree no longer removes a tree with
	unreadable subdirectories, such as we (intentionally) have.  So we
	might as well go back to rm -rf.  The unconditional recursive chmod
	instead of the previously-used more complex find command will
	hopefully prove portable.  See the bug report for more details.

	Our deltree.pl is not used for anything else, but nevertheless
	leaving it in our source tree for now, for ease of reversion
	and comparison.

2020-01-08  Karl Berry  <karl@freefriends.org>

	tests: use skip_ consistently.

	* t/lisp-loadpath.sh: use skip_ instead of exit 77;
	also, notice and reset if the EMACS envvar is simply "t".
	* t/uninstall-fail.sh: use skip_ instead of the undefined skip.

2020-01-05  Karl Berry  <karl@freefriends.org>

	tests: Correctly simulate no emacs in t/nobase-nodist.sh

	* t/nobase-nodist.sh: export EMACS, not EMCAS, as "no".

2020-01-04  Karl Berry  <karl@freefriends.org>

	automake: Support byte compilation in older Emacsen

	* lib/am/lisp.am (am__emacs_byte_compile_setup) [FIRST]: define
	new make variable, to use byte-compile-dest-file-function if
	available, else byte-compile-dest-file.
	(.el.elc): use it.
	* t/lisp-loadpath.sh: skip test if emacs version is <= 23,
	since their -L ordering is backwards.
	* NEWS: update.

2019-11-17  Giuseppe Scrivano  <gscrivan@redhat.com>
