Log message:
Mention the files in mk/gnu-config that should be updated when updating
autoconf.

Log message:
Bump PKGREVISION for updated config.* files (see mk/gnu-config
commit from today).

Log message:
Bump all packages for perl-5.18, that
a) refer 'perl' in their Makefile, or
b) have a directory name of p5-*, or
c) have any dependency on any p5-* package

Like last time, where this caused no complaints.

Log message:
Drop superfluous PKG_DESTDIR_SUPPORT, "user-destdir" is default these days.

Log message:
Bump all packages that use perl, or depend on a p5-* package, or
are called p5-*.

I hope that's all of them.

Log message:
Update to 2.69:

* Noteworthy changes in release 2.69 (2012-04-24) [stable]

** Autoconf now requires perl 5.6 or better (but generated configure
   scripts continue to run without perl).

* Noteworthy changes in release 2.68b (2012-03-01) [beta]
  Released by Eric Blake, based on git versions 2.68.*.

** Autoconf-generated configure scripts now unconditionally re-execute
   themselves with $CONFIG_SHELL, if that's set in the environment.

** The texinfo documentation no longer specifies "front-cover" or
   "back-cover" texts, so that it may now be included in Debian's
   "main" section.

** Support for the Go programming language has been added.  The new macro
   AC_LANG_GO sets variables GOC and GOFLAGS.

** AS_LITERAL_IF again treats '=' as a literal.  Regression introduced in
   2.66.

** The macro AS_EXECUTABLE_P, present since 2.50, is now documented.

** Macros

- AC_PROG_LN_S and AS_LN_S now fall back on 'cp -pR' (not 'cp -p') if 'ln -s'
  does not work.  This works better for symlinks to directories.

- New macro AC_HEADER_CHECK_STDBOOL.

- New and updated macros for Fortran support:

    AC_FC_CHECK_BOUNDS to enable array bounds checking
    AC_F77_IMPLICIT_NONE and AC_FC_IMPLICIT_NONE to disable implicit integer
    AC_FC_MODULE_EXTENSION to compute the Fortran 90 module name extension
    AC_FC_MODULE_FLAG for the Fortran 90 module search path flag
    AC_FC_MODULE_OUTPUT_FLAG for the Fortran 90 module output directory flag
    AC_FC_PP_SRCEXT for preprocessed Fortran source files extensions
    AC_FC_PP_DEFINE for the Fortran preprocessor define flag

Log message:
Add build dependency on help2man to get all man pages properly
formatted.

Log message:
Update CONFLICTS so that devel/gdb doesn't conflict with autoconf.

Bump PKGREVISION.

Log message:
Update to 2.68, requested by adam for pkg-config-0.25.

* Noteworthy changes in release 2.68 (2010-09-22) [stable]
  Released by Eric Blake, based on git versions 2.67.*.

** AC_MSG_ERROR (and AS_ERROR) can once again be followed immediately by
   `dnl'.  Regression introduced in 2.66.

** AC_INIT again allows URLs with '?' for its BUG-REPORT argument.
   Regression introduced in 2.66.

** AC_REPLACE_FUNCS again allows a non-literal argument, such as a shell
   variable that expands to a list of functions to check.  Regression
   introduced in 2.66.

** AT_BANNER() with empty argument will cause visual separation from previous
   test category.

** The macros AC_PREPROC_IFELSE, AC_COMPILE_IFELSE, AC_LINK_IFELSE, and
   AC_RUN_IFELSE now warn if the first argument failed to use
   AC_LANG_SOURCE or AC_LANG_PROGRAM to generate the conftest file
   contents.  A new macro AC_LANG_DEFINES_PROVIDED exists if you have
   a compelling reason why you cannot use AC_LANG_SOURCE but must
   avoid the warning.

** The macro m4_define_default is now documented.

** Symlinked config.cache files are supported; configure now tries to
   update non-symlinked cache files atomically, so that concurrent configure
   runs do not leave behind broken cache files.  It is still unspecified
   which subset or union of results is cached though.

** Autotest testsuites should not contain long text lines any more, and be
   portable even when very many test groups are used.

** AT_CHECK semantics with respect to the Autotest variable $at_status and
   shell execution environment of the arguments are documented now.

** AC_FC_LIBRARY_LDFLAGS now tolerates output from newer gfortran.

** Newly obsolete macros
   The following macros have been marked obsolete.  New programs
   should use the corresponding Gnulib modules.  Gnulib not only
   detects a larger set of portability problems with these functions,
   but also provides complete workarounds.

     AC_FUNC_ERROR_AT_LINE  AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK
     AC_FUNC_MKTIME  AC_FUNC_STRTOD

Log message:
Update to 2.67:

* Major changes in Autoconf 2.67 (2010-07-21) [stable]
  Released by Eric Blake, based on git versions 2.66.*.

** 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.

* Major changes in Autoconf 2.66 (2010-07-02) [stable]
  Released by Eric Blake, based on git versions 2.65.*.

** 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.
