A new release of m4, 1.4.17-2, will soon be available on your favorite mirror, leaving 1.4.17-1 as previous. NEWS: ===== This is a refresh build, done in order to let 64-bit m4 take advantage of new stack overflow detection code supported by cygwin 2.1. Ideally, you won't notice any change of behavior except on poor input files that cause stack overflow due to indefinite nesting. 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. If you encounter a problem that might be cygwin-specific, please report it here rather than upstream. See also the upstream documentation in /usr/share/doc/m4/. 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 look for 'm4' in the 'Interpreters' category. DOWNLOAD: ========= Note that downloads from 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 package maintainer For more details on this list (including unsubscription), see: http://sourceware.org/lists.html
