Simon Marchi d0ac1c4488 Bump to autoconf 2.69 and automake 1.15.1
When trying to run the update-gnulib.sh script in gdb, I get this:

Error: Wrong automake version (Unescaped left brace in regex is deprecated, passed through in regex; marked by <-- HERE in m/\${ <-- HERE ([^      =:+{}]+)}/ at /opt/automake/1.11.1/bin/automake line 4113.), we need 1.11.1.
Aborting.

Apparently, it's an issue with a regex in automake that triggers a
warning starting with Perl 5.22.  It has been fixed in automake 1.15.1.
So I think it's a good excuse to bump the versions of autoconf and
automake used in the gnulib import.  And to avoid requiring multiple
builds of autoconf/automake, it was suggested that we bump the required
version of those tools for all binutils-gdb.

For autoconf, the 2.69 version is universally available, so it's an easy
choice.  For automake, different distros and distro versions have
different automake versions.  But 1.15.1 seems to be the most readily
available as a package.  In any case, it's easy to build it from source.

I removed the version checks from AUTOMAKE_OPTIONS and AC_PREREQ,
because I don't think they are useful in our case.  They only specify a
lower bound for the acceptable version of automake/autoconf.  That's
useful if you let the user choose the version of the tool they want to
use, but want to set a minimum version (because you use a feature that
was introduced in that version).  In our case, we force people to use a
specific version anyway.  For the autoconf version, we have the check in
config/override.m4 that enforces the version we want.  It will be one
less thing to update next time we change autotools version.

I hit a few categories of problems that required some changes.  They are
described below along with the chosen solutions.

Problem 1:

  configure.ac:17: warning: AM_INIT_AUTOMAKE: two- and three-arguments forms are deprecated.  For more info, see:
  configure.ac:17: http://www.gnu.org/software/automake/manual/automake.html#Modernize-AM_005fINIT_005fAUTOMAKE-invocation

Solution 1:

  Adjust the code based on the example at that URL.

Problem 2 (in zlib/):

  Makefile.am: error: required file './INSTALL' not found
  Makefile.am:   'automake --add-missing' can install 'INSTALL'
  Makefile.am: error: required file './NEWS' not found
  Makefile.am: error: required file './AUTHORS' not found
  Makefile.am: error: required file './COPYING' not found
  Makefile.am:   'automake --add-missing' can install 'COPYING'

Solution 2:

  Add the foreign option to AUTOMAKE_OPTIONS.

Problem 3:

  doc/Makefile.am:20: error: support for Cygnus-style trees has been removed

Solution 3:

  Remove the cygnus options.

Problem 4:

  Makefile.am:656: warning: 'INCLUDES' is the old name for 'AM_CPPFLAGS' (or '*_CPPFLAGS')

Solution 4:

  Rename "INCLUDES = " to "AM_CPPFLAGS += " (because AM_CPPFLAGS is
  already defined earlier).

Problem 5:

  doc/Makefile.am:71: warning: suffix '.texinfo' for Texinfo files is discouraged; use '.texi' instead
  doc/Makefile.am: warning: Oops!
  doc/Makefile.am:     It appears this file (or files included by it) are triggering
  doc/Makefile.am:     an undocumented, soon-to-be-removed automake hack.
  doc/Makefile.am:     Future automake versions will no longer place in the builddir
  doc/Makefile.am:     (rather than in the srcdir) the generated '.info' files that
  doc/Makefile.am:     appear to be cleaned, by e.g. being listed in CLEANFILES or
  doc/Makefile.am:     DISTCLEANFILES.
  doc/Makefile.am:     If you want your '.info' files to be placed in the builddir
  doc/Makefile.am:     rather than in the srcdir, you have to use the shiny new
  doc/Makefile.am:     'info-in-builddir' automake option.

Solution 5:

  Rename .texinfo files to .texi.

Problem 6:

  doc/Makefile.am: warning: Oops!
  doc/Makefile.am:     It appears this file (or files included by it) are triggering
  doc/Makefile.am:     an undocumented, soon-to-be-removed automake hack.
  doc/Makefile.am:     Future automake versions will no longer place in the builddir
  doc/Makefile.am:     (rather than in the srcdir) the generated '.info' files that
  doc/Makefile.am:     appear to be cleaned, by e.g. being listed in CLEANFILES or
  doc/Makefile.am:     DISTCLEANFILES.
  doc/Makefile.am:     If you want your '.info' files to be placed in the builddir
  doc/Makefile.am:     rather than in the srcdir, you have to use the shiny new
  doc/Makefile.am:     'info-in-builddir' automake option.

Solution 6:

  Remove the hack at the bottom of doc/Makefile.am and use
  the info-in-builddir automake option.

Problem 7:

  doc/Makefile.am:35: error: required file '../texinfo.tex' not found
  doc/Makefile.am:35:   'automake --add-missing' can install 'texinfo.tex'

Solution 7:

  Use the no-texinfo.tex automake option.  We also have one in
  texinfo/texinfo.tex, not sure if we should point to that, or move it
  (or a newer version of it added with automake --add-missing) to
  top-level.

Problem 8:

  Makefile.am:131: warning: source file 'config/tc-aarch64.c' is in a subdirectory,
  Makefile.am:131: but option 'subdir-objects' is disabled
  automake: warning: possible forward-incompatibility.
  automake: At least a source file is in a subdirectory, but the 'subdir-objects'
  automake: automake option hasn't been enabled.  For now, the corresponding output
  automake: object file(s) will be placed in the top-level directory.  However,
  automake: this behaviour will change in future Automake versions: they will
  automake: unconditionally cause object files to be placed in the same subdirectory
  automake: of the corresponding sources.
  automake: You are advised to start using 'subdir-objects' option throughout your
  automake: project, to avoid future incompatibilities.

Solution 8:

  Use subdir-objects, that means adjusting references to some .o that will now
  be in config/.

Problem 9:

  configure.ac:375: warning: AC_LANG_CONFTEST: no AC_LANG_SOURCE call detected in body
  ../../lib/autoconf/lang.m4:193: AC_LANG_CONFTEST is expanded from...
  ../../lib/autoconf/general.m4:2601: _AC_COMPILE_IFELSE is expanded from...

  ../../lib/autoconf/general.m4:2063: AC_CACHE_CHECK is expanded from...
  configure.ac:375: the top level

Solution 9:

  Use AC_LANG_SOURCE, or use proper quoting.

Problem 10 (in intl/):

  configure.ac:7: warning: AC_COMPILE_IFELSE was called before AC_USE_SYSTEM_EXTENSIONS
  /usr/share/aclocal/threadlib.m4:36: gl_THREADLIB_EARLY_BODY is expanded from...

  Add AC_USE_SYSTEM_EXTENSIONS in configure.ac.

		   README for GNU development tools

This directory contains various GNU compilers, assemblers, linkers, 
debuggers, etc., plus their support routines, definitions, and documentation.

If you are receiving this as part of a GDB release, see the file gdb/README.
If with a binutils release, see binutils/README;  if with a libg++ release,
see libg++/README, etc.  That'll give you info about this
package -- supported targets, how to use it, how to report bugs, etc.

It is now possible to automatically configure and build a variety of
tools with one command.  To build all of the tools contained herein,
run the ``configure'' script here, e.g.:

	./configure 
	make

To install them (by default in /usr/local/bin, /usr/local/lib, etc),
then do:
	make install

(If the configure script can't determine your type of computer, give it
the name as an argument, for instance ``./configure sun4''.  You can
use the script ``config.sub'' to test whether a name is recognized; if
it is, config.sub translates it to a triplet specifying CPU, vendor,
and OS.)

If you have more than one compiler on your system, it is often best to
explicitly set CC in the environment before running configure, and to
also set CC when running make.  For example (assuming sh/bash/ksh):

	CC=gcc ./configure
	make

A similar example using csh:

	setenv CC gcc
	./configure
	make

Much of the code and documentation enclosed is copyright by
the Free Software Foundation, Inc.  See the file COPYING or
COPYING.LIB in the various directories, for a description of the
GNU General Public License terms under which you can copy the files.

REPORTING BUGS: Again, see gdb/README, binutils/README, etc., for info
on where and how to report problems.
