Autoconf is an extensible package of m4 macros that produce shell
scripts to automatically configure software source code packages.  The
autoconf2.5 package contains the latest edition of autoconf in the 2.5x
release sequence (which includes 2.60, 2.61, etc).

Changes since autoconf2.5-2.65-1
======================================================================
* update to latest upstream release
  + see list of upstream changes below
* Include Debian patchset 2.67-2

Testsuite results:
======================================================================
ERROR: 469 tests were run,
6 failed (4 expected failures).
8 tests were skipped.

Unexpected failed tests were:
193: parallel test execution         FAILED (autotest.at:1312)
  Had to manually kill the test, because it was hung for over an hour.

197: parallel syntax error           FAILED (autotest.at:1356)
  Ditto.

Cygwin's autoconf-2.65 package also had some issues with the parallel
tests (slightly different: previously microsuite actually reported
a failure).  So, I don't consider this a regression in autoconf;
although it's possible cygwin itself has regressed.


Note that I ran the tests with LANG=en_US.UTF-8


Upstream changes (2.67):
======================================================================
The GNU Autoconf team is pleased to announce the stable release of
Autoconf 2.67.  Autoconf is an extensible package of M4 macros that
produce shell scripts to automatically configure software source code
packages.  These scripts can adapt the packages to many kinds of
UNIX-like systems without manual user intervention.  Autoconf creates a
configuration script for a package from a template file that lists the
operating system features that the package can use, in the form of M4
macro calls.

This release fixes a few regressions introduced in the previous release,
and is primarily focused on bug fixes.  It also includes a few new
features, documented below.

** AC_CONFIG_SUBDIRS with more than one subdirectory at a time works again.
   Regression introduced in 2.66.

** AC_CHECK_SIZEOF of a pointer type works again.  Regression introduced in
   2.66.

** New macro AC_FC_LINE_LENGTH to accept long Fortran source code lines.

** AC_PREPROC_IFELSE now keeps the preprocessed output in the conftest.i
   file for inspection by the commands in the ACTION-IF-TRUE argument.

** AC_INIT again allows parentheses and other characters that are literal
   in single- or double-quoted strings, and in quoted and unquoted
   here-documents, for its PACKAGE and VERSION arguments.  Regression
   introduced in 2.66.

** autoreconf passes warning flags to new enough versions of aclocal.

** Running an Autotest testsuite in parallel mode no longer triggers a
   race condition that could cause the testsuite run to end early,
   fixing a sporadic failure in autoconf's own testsuite.  Bug present
   since introduction of parallel tests in 2.63b.


Upstream changes (2.66):
======================================================================
The GNU Autoconf team is pleased to announce the stable release of
Autoconf 2.66.  Autoconf is an extensible package of M4 macros that
produce shell scripts to automatically configure software source code
packages.  These scripts can adapt the packages to many kinds of
UNIX-like systems without manual user intervention.  Autoconf creates a
configuration script for a package from a template file that lists the
operating system features that the package can use, in the form of M4
macro calls.

This release fixes a few regressions introduced in recent releases, and
is primarily focused on bug fixes.  It also includes a few new features,
documented below.

** AC_FUNC_MMAP works in C++ mode again.  Regression introduced in 2.65.

** Use of m4_divert without a named diversion now issues a syntax warning,
   since it is seldom right to change diversions behind autoconf's back.

** The macros AC_TYPE_INT8_T, AC_TYPE_INT16_T, AC_TYPE_INT32_T, and
   AC_TYPE_INT64_T work again.  Regression introduced in 2.65.

** AC_PROG_INSTALL correctly uses `shtool' again.  Regression introduced
   in 2.64.

** Autoconf should work on EBCDIC hosts.

** AC_CHECK_DECL and AC_CHECK_DECLS accept optional function argument types
   for overloaded C++ functions.

** AS_SET_CATFILE accepts nonliterals in its variable name argument now.

** Autotest testsuites accept an option --recheck to rerun tests that
   failed or passed unexpectedly during the last non-debug testsuite run.

** AC_ARG_ENABLE and AC_ARG_WITH now also accept `+' signs in `--enable-*'
   and `--with-*' arguments, converting them to underscores for the variable
   names.

** In configure scripts, loading CONFIG_SITE no longer searches PATH,
   and problems in loading the configuration site files are diagnosed.

** Autotest testsuites may optionally provide colored test results.

** The previously undocumented Autotest macros AT_ARG_OPTION and
   AT_ARG_OPTION_ARG have seen bug fixes and are documented now.
   AT_ARG_OPTION has been changed in that the negative of a long option
   --OPTION is now --no-OPTION rather than --noOPTION.

** The macro AS_LITERAL_IF is slightly more conservative; text
   containing shell quotes are no longer treated as literals.
   Furthermore, a new macro, AS_LITERAL_WORD_IF, adds an additional
   level of checking that no whitespace occurs in literals.

** The macros AS_TR_SH and AS_TR_CPP no longer expand their results.

** The following macros are now documented:
   AS_BOX

** New macro AC_FC_FIXEDFORM to accept fixed-form Fortran.

New in 2.65
====================================================================
* Major changes in Autoconf 2.65 (2009-11-21) [stable]
  Released by Eric Blake, based on git versions 2.64.*.

** Autoconf is now licensed under the General Public License version 3
   or later (GPLv3+).  As with earlier versions, the license includes
   an exception clause so that you may release a configure script
   generated by autoconf under the license of your own program.

** New macros to support Objective C++.
   AC_PROG_OBJCXX  AC_PROG_OBJCXXCPP

** The following undocumented autoconf macros, removed in Autoconf 2.64,
   have been reinstated:
   AH_CHECK_HEADERS

   These macros are present only for backwards compatibility purposes.

** The macro AC_LANG_COMPILER no longer fails on embedded systems that
   lack fopen in the C library, such as AVR or RTEMS (regression
   introduced in 2.64).

** The AC_FC_FREEFORM macro no longer suffers from a whitespace bug that
   made it fail with some Fortran compilers (regression introduced in
   2.64).

** The AC_TYPE_UINT64_T and AC_TYPE_INT64_T macros have been fixed to no
   longer mistakenly select a 32-bit type on some compilers (bug present
   since macros were introduced in 2.59c).

** The AC_FUNC_MMAP macro has been fixed to be portable to systems like
   Cygwin (bug present since macro was introduced in 2.0).

** The following documented autotest macros are new:
   AT_CHECK_EUNIT

** The following m4sugar macros now quote their expansion:
   m4_toupper  m4_tolower

** The following m4sugar macros are new:
   m4_escape

** The m4sugar macro m4_text_wrap now copes with embedded quoting without
   requiring quadrigraphs.  For uses like AC_ARG_VAR([a], [[b c]]),
   this gives the intuitive behavior of "[b c]" in the output (2.63
   gave the output of "[b], [c]", and 2.64 encountered a failure).

** The `$tmp' temporary directory used in config.status is documented for
   public use now.

** config.status now provides a --config option to produce the configuration.

** Many cache variables used by Autoconf's macros are now documented.

** Configure scripts work better on DJGPP by avoiding a bug present in
   the DJGPP port of bash 2.04 in handling 'return' in a shell
   function (regression introduced in 2.64).
