NEWS ==== This is a new upstream release. The previous version, 1.4.10b, was a beta preview of the eventual m4 1.6, and as such, has some optimizations that make it faster than 1.4.13 in some situations. However, the benefits of using 1.4.13 include new stack overflow detection (thanks to libsigsegv), and some bug fixes not present in 1.4.10b. An excerpt from the NEWS file is attached; see also /usr/share/doc/m4/. You must rebuild from source if you want the experimental changeword feature enabled, as using it can slow down normal operation, and since it will disappear from the eventual m4 2.0. DESCRIPTION =========== m4 is an implementation of the traditional Unix macro processor. It is mostly SVR4 compatible although it has some extensions (for example, handling more than 9 positional parameters to macros). GNU m4 also has built-in functions for including files, running shell commands, doing arithmetic, etc. UPDATE ====== To update your installation, click on the "Install Cygwin now" link on the http://cygwin.com/ web page. This downloads setup.exe to your system. Save it and run setup, answer the questions and pick up 'm4' from the 'Interpreters' category. DOWNLOAD: ========= Note that downloads from sources.redhat.com (aka cygwin.com) aren't allowed due to bandwidth limitations. This means that you will need to find a mirror which has this update, please choose the one nearest to you: http://cygwin.com/mirrors.html QUESTIONS: ========== If you want to make a point or ask a question the Cygwin mailing list is the appropriate place. - -- Eric Blake volunteer cygwin m4 maintainer CYGWIN-ANNOUNCE UNSUBSCRIBE INFO: ================================= To unsubscribe to the cygwin-announce mailing list, look at the "List-Unsubscribe: " tag in the email header of this message.

You must therefore use `m4 --debugfile=trace file', not `m4 file --debugfile trace'. This change does not affect the deprecated `-o'/`--error-output' option. ** The `syscmd' and `esyscmd' builtins can be configured to use an alternate shell, via the new `configure' option `--with-syscmd-shell'. ** A number of portability improvements inherited from gnulib. * Noteworthy changes in Version 1.4.12 (2008-10-10) [stable] Released by Eric Blake, based on git version 1.4.11.* ** Fix regression introduced in 1.4.4b where using `traceon' could delete a macro. This was most noticeable with `traceon(`traceon')', but would also happen in cases such as `foo(traceon(`foo'))'. ** Fix regression introduced in 1.4.7 where `m4 -N9' died with an assertion failure. ** Fix regression introduced in 1.4.11 where `defn' died with an assertion failure on a traced but undefined macro. ** New `-g'/`--gnu' command-line option overrides `-G'/`--traditional'. For now, the environment variable POSIXLY_CORRECT has no effect on M4 behavior; but a future release of M4 will behave as though --traditional is implied if POSIXLY_CORRECT is set (this future change is necessary, because in the current release, there is no way to disable GNU extensions that conflict with POSIX without the use of a non-POSIX command-line argument). Clients of M4 that want to use GNU extensions, even when POSIXLY_CORRECT is set, should start using the -g command-line argument, even though it is currently a no-op if -G did not appear earlier in the command line, so that the client will not break in the face of an upgraded m4 and a POSIXLY_CORRECT execution environment. ** The `-L'/`--nesting-limit' command-line option now defaults to 0 for unlimited on platforms that can detect and deal with stack overflow. On systems that lack alternate stack support, such as Cygwin, and on systems that do not obey the POSIX semantics for distinguishing stack overflow from other exceptions, such as Linux, you can optionally install the libsigsegv library (version 2.6 or newer recommended) to enhance m4's ability to accurately report stack overflow: http://www.gnu.org/software/libsigsegv/ ** A number of portability improvements inherited from gnulib. * Noteworthy changes in Version 1.4.11 (2008-04-02) [stable] Released by Eric Blake, based on git version 1.4.10a ** Security fixes for the -F option, for bugs present since -F was introduced in 1.3: Avoid core dump with 'm4 -F file -t undefined', and avoid arbitrary code execution with certain file names. ** Fix regression introduced in 1.4.9b in the `divert' builtin when more than 512 kibibytes are saved in diversions on platforms like NetBSD or darwin where fopen(name,"a+") seeks to the end of the file. ** The output of the `maketemp' and `mkstemp' builtins is now quoted if a file was created. This is a minor security fix, because it was possible (although rather unlikely) that an unquoted string could match an existing macro name, such that use of the `mkstemp' output would trigger inadvertent macro expansion and operate on the wrong file name. ** Enhance the `defn' builtin to support concatenation of multiple text arguments, as required by POSIX. However, at this time, it is not possible to concatenate a builtin macro with anything else; a warning is now issued if this is attempted, although a future version of M4 may lift this restriction to match other implementations. ** Enhance the `format' builtin to parse all C99 floating point numbers, even on platforms where strtod(3) is buggy, although the replacement function does have the known issue of rounding errors when parsing some decimal floating point values. This fixes testsuite failures introduced in 1.4.9b. ** Enhance the `index' builtin to guarantee linear behavior, in spite of the surprisingly large number of systems with a brain-dead quadratic strstr(3). ** A number of portability improvements inherited from gnulib. --------------000800030908030601030903--
