Log Message:
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.
