Log message:
Add patch from Bruno Haible (upstream) fixing two of the included
gnulib tests that were broken on NetBSD-4.99.58/amd64.

Bump PKGREVISION.

Log message:
Convert to use PLIST_VARS instead of manually passing "@comment "
through PLIST_SUBST to the plist module.

Log message:
add hacks.mk to work around a compiler optimization error with
gcc on solaris.

Log message:
Override gnulib's fflush.c on DragonFly with a far less intrusive
versions. This is still in discussion with upstream, but working m4
is critical, so apply this stop-gap solution. It works on the other
BSD derived stdio implementations as well, if you want to switch.

Log message:
Update to 1.4.10nb1. Like previous update to 1.4.10, but includes
a patch from Eric Blake that fixes the problem that appeared e.g.
in dosbox or mng.

Log message:
Update to 1.4.10. Add commented out LICENSE=GPLv3 line.

Version 1.4.10 - 09 Jul 2007, by Eric Blake  (CVS version 1.4.9c)

* Upgrade from GPL version 2 to GPL version 3 or later.
* A number of portability improvements inherited from gnulib.
* Avoid undefined behavior introduced in 1.4.9b in the `format' builtin
  when handling %c.  However, this area of code has never been documented,
  and currently does not match the POSIX behavior of printf(1), so it may
  have further changes in the next version.

Version 1.4.9b - 29 May 2007, by Eric Blake  (CVS version 1.4.9a)

* Fix regression introduced in 1.4.9 in the `eval' builtin when performing
  division.
* Fix regression introduced in 1.4.8 in the `-F' option that made it
  impossible to freeze more than 512 kibibytes of diverted text.
* The synclines option `-s' no longer generates sync lines in the middle of
  multiline comments or quoted strings.
* Work around a number of corner-case POSIX compliance bugs in various
  broken stdio libraries.  In particular, the `syscmd' builtin behaves
  more predictably when stdin is seekable.
* The `format' builtin now understands formats such as %a, %A, and %'hhd,
  and works around a number of platform printf bugs.  Furthermore, the
  sequence format(%*.*d,-1,-1,1) no longer outputs random data.  However,
  some non-compliant platforms such as mingw still have known bugs in
  strtod that may cause testsuite failures.
* The testsuite is improved to also run gnulib portability tests for the
  features that M4 imports from gnulib.

Log message:
Fix a division bug when negative numbers are involved.  Bump pkgrev.

Update to 1.4.9:

Version 1.4.9 - 23 Mar 2007, by Eric Blake  (CVS version 1.4.8c)

* Minor documentation and portability cleanups.

Version 1.4.8b - 24 Feb 2007, by Eric Blake  (CVS version 1.4.8a)

* Fix a regression introduced in 1.4.8 that made m4 unable to process
  files larger than 2GiB on some platforms.
* Fix a regression introduced in 1.4.8 that made m4 dump core when
  invoked as 'm4 -- file'.
* The `eval' builtin now follows C precedence rules.  Additionally, the
  short-circuit operators correctly short-circuit division by zero.  The
  previously undocumented alias of '=' meaning '==' in eval now triggers a
  deprecation warning, so that a future version of M4 can implement a form
  of variable assignment as an extension.
* The `include' builtin now affects exit status on failure, as required by
  POSIX.  Use `sinclude' if you need a successful exit status.
* The `-E'/`--fatal-warnings' command-line option now has two levels.  When
  specified only once, warnings affect exit status, but execution
  continues, so that you can see all warnings instead of fixing them one
  at a time.  To acheive 1.4.8 behavior, where the first warning
  immediately exits, specify -E twice on the command line.
* A new `--warn-macro-sequence' command-line option allows detection of
  sequences in `define' and `pushdef' definitions that match an optional
  regular expression.  The default regular expression is
  `\$\({[^}]*}\|[0-9][0-9]+\)', corresponding to the sequences that might
  not behave correctly when upgrading to the eventual M4 2.0.  By default,
  M4 2.0 will follow the POSIX requirement that a macro definition
  containing `$11' must expand to the first argument concatenated with 1,
  rather than the eleventh argument; and will take advantage of the POSIX
  wording that allows implementations to treat `${11}' as the eleventh
  argument instead of literal text.  Be aware that Autoconf 2.61 will not
  work with this option enabled with the default regular expression; but
  Autoconf 2.62 will be compatible with this option.
* Improved portability to platforms such as BSD/OS and AIX.

Update to 1.4.8:

Version 1.4.8 - 20 November 2006, by Eric Blake  (CVS version 1.4.7a)

* The `divert' macro and `-H'/`--hashsize' command line option no longer
  cause a core dump when handed extra large values.  Also, `divert' now
  uses memory proportional to the number of diversions in use, rather than
  to the maximum diversion number encountered, so that large diversion
  numbers are less likely to exhaust system memory; and is no longer
  limited by the maximum number of file descriptors.
* The `--help' and `--version' command line options now consistently
  override all earlier options.  For example, `m4 --debugfile=trace
  --help' now no longer accidentally creates an empty file `trace'.
* The `-L'/`--nesting-limit' command line option can now be set to 0
  to remove the default limit of 1024.  However, it is still possible that
  heavily nested input can cause abrupt program termination due to stack
  overflow.
* Problems encountered when writing to standard error, such as with the
  `errprint' macro, now always cause a non-zero exit status.
* Warnings and errors issued during macro expansion are now consistently
  reported at the line where the macro name was detected, rather than
  where the close parenthesis resides.  Text wrapped by `m4wrap' now
  remembers the location that was in effect when m4wrap was invoked,
  rather than changing to line 0 and the empty string for a file.  The
  macros `__line__' and `__file__' now work correctly even as the last
  token in an included file.
* The `builtin' and `indir' macros now transparently handle builtin
  tokens generated by `defn'.
* When diversions created by the `divert' macro collect enough text that
  M4 must use temporary files, the environment variable $TMPDIR is now
  consulted, and a better effort is made to clean up those files in the
  event of a fatal signal.
* The `mkstemp' builtin is added with the same GNU semantics as `maketemp',
  based on the recommendation of POSIX to deprecate the POSIX semantics of
  `maketemp' as inherently insecure.  In GNU mode (no -G supplied on the
  command line), `maketemp' silently retains the secure GNU semantics, but
  a future release of M4 will change this to emit a warning.  In
  traditional mode (m4 -G), `maketemp' now uses the POSIX-mandated insecure
  semantics, and issues a warning that you should convert your script to
  use `mkstemp' instead.  Additionally, `mkstemp' and `maketemp' are now
  well-defined even if the template argument does not end in six `X'
  characters.
* The manual has been improved, including a new section on a composite
  macro `foreach'.
* The `changecom' and `changequote' macros now treat an empty second
  argument the same as if it were missing, rather than using the empty
  string and making it impossible to end a comment or quote.
* The `translit' macro now operates in linear instead of quadratic time,
  and is now eight-bit clean.
* The `-D', `-U', `-s', and `-t' command line options now take effect
  after any files encountered earlier on the command line, rather than up
  front, as is done in traditional implementations and required by POSIX.
