This reduces the implicit requirement from 5.6.2 back to 5.6,
while raising the explicit requirement to match the actual code.
* configure.ac (PERL): Fail up front if perl is too old.
* NEWS: Document this.
* README: Likewise.
* README-hacking: Likewise.
* lib/Autom4te/ChannelDefs.pm: Bump requirement.
* lib/Autom4te/General.pm: Relax requirement.
Since the perl version required in Automake::Getopt has been
recently lowered from 5.6.2 to 5.6.0, this change has the nice
effect of making autoconf compatible again with all perls in
the 5.6.x release series.
* maint.mk: Resync via 'make fetch'.

The module Automake::Struct has been removed in automake master
branch (with yesterday's commit v1.11-2055-g74a7f49 "maint: drop
'Automake::Struct' module"): since Automake now requires Perl 5.6,
that module has become obsolete, being basically just a backport
of Perl 5.6's 'Class::Struct' to Perl 5.5. With this change, we
follow suite in Autoconf, which syncs some of its internal modules
with Automake.
* lib/Autom4te/Struct.pm: Delete.
* lib/Autom4te/Makefile.am (dist_perllib_DATA): Don't list it
anymore.
* cfg.mk: Don't sync it with the Automake repository anymore.
* lib/Autom4te/Request.pm: Use 'Class::Struct' instead of
'Autom4te::Struct'.
* lib/Autom4te/Getopt.am: The master copy of this file has
been moved to the Automake repository (see Automake commit
'v1.11-662-g52246cc' 2012-01-18, "cmdline parsing: move into
a dedicated perl module"). So we now we sync it from there,
by listing it ...
* cfg.mk (autom4te_files): ... in this variable.
* lib/Autom4te/General.pm (getopt): Move the guts of its
implementation ...
* lib/Autom4te/Getopt.pm (parse_options): .. into this function
in the new Autom4te::Getopt module. This will make it simpler
for the implementation to be shared with other projects (right
now, Automake).
* lib/Automake/Makefile.am (dist_perllib_DATA): Add the new
module.
Older versions of Getopt::Long acted bogusly and died when they
where configured with the 'bundling' flag and an argument '-' was
seen on the command line they were parsing. That is no longer
the case though, and has not been for quite a long time: the bug
is no longer present in the 5.6.2 version of perl and the 2.25
version of Getopt::Long (and today, the latest versions of perl
and Getopt::Long are respectively 5.14.2 and 2.38). The obsolete
workaround for that Getopt::Long bug can thus be removed from our
'getopt' function.
It is also worth noting that such a workaround was quite buggy
and brittle itself; for example, a command like this:
"autom4te --output -"
would have caused the incorrect diagnostic:
"autom4te: option `--output' requires an argument"
Much worse, a command like this:
"autom4te --language=autoconf --output - configure.ac"
would have caused the standard input of autom4te to be processed
and copied into the 'configure.ac' file, deleting its pre-existing
content! Surely not what a user would have expected.
After this change, a command like this:
autom4te --language=autoconf --output - - <configure.ac >out
works as expected, processing the input from 'configure.ac' and
writing it to the 'out' file.
* lib/Autom4te/General.pm (use): Require perl version 5.6.2.
(getopt): Remove the old workaround.
Before this change, an incorrect command line usage:
"autom4te --output"
triggered broken diagnostic like:
"autom4te: unrecognized option `--output'"
instead of the expected and correct:
"autom4te: option `--output' requires an argument"
* lib/Autom4te/General.pm (getopt): Give correct diagnostic in
case of usage errors due to missing arguments for options for
which they are mandatory. Code basically copied from automake's
'parse_arguments' private subroutine.
* lib/Autom4te/ChannelDefs.pm, lib/Autom4te/Channels.pm,
lib/Autom4te/General.pm: Fix typos and spacing in perlpod
documentation and in comments.

* lib/Autom4te/ChannelDefs.pm (Autom4te::ChannelDefs): Set
`ordered' flag to zero for channels `fatal', `automake', and
`verb'. This has currently no effect on actual semantics but
avoids a consistency check needed for Automake's usage of the
Channels.pm code.

Return back to GPLv2+, until the text of the exceptions is
finalized, reverting the change from 2007-07-03 and the first
part of the change from 2007-07-20.

* COPYING: Revert to GPLv2.
* COPYINGv3: New file, since some auxiliary build tools, used for
building autoconf and not installed, are GPLv3.
* Makefile.am (EXTRA_DIST): Distribute COPYINGv3.
* NEWS: Remove mention of GPLv3.
* README: Clarify situation regarding GPLv3.

This includes escaping of characters special to the shell
as well as special to Perl, e.g., leading `<' or `>'.
For example, when $file starts with `>', `open ">$file"'
wrongly tries to append to a different file.
* bin/autoconf.as: Fix quoting for autom4te options.
* lib/Autom4te/General.pm (shell_quote): New function, taken
from coreutils, written by Jim Meyering.
(mktmpdir): Use it.
* bin/autom4te.in (files_to_options, handle_m4): Use shell_quote
and open_quote.
* bin/autoreconf.in (parse_args): Likewise.
* bin/autoscan.in (main): Likewise.

* bin/autoheader.in: Likewise, fixing old insufficient escaping.

test. Test twice, with special characters allowed on w32, and the
rest. Test leading and trailing whitespace, for `open_quote'.
(autotools and whitespace in file names): New, analogous test.

* .gitignore: Add aclocal.m4, configure and Makefile.in. Sort.
* README-hacking: New file: how to build from just-checked-out sources.
* build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
which incorrectly sets the mode of an existing destination
directory. In some cases the unpatched install-sh could do the
equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
system. We hope this is rare in practice, but it's clearly worth
fixing. Problem reported by Alex Unleashed in
<http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
Also, don't bother to check for -m bugs unless we're using -m;
