You are using a AC_CONFIG_FILES now instead of a AC_CONFIG_HEADERS. That's fine per se, but config files are updated unconditionally by config.status, meaning that the updated timestamp might cause more rebuilds than necessary. > The next thing I want to add is a MYLIB_VERSION_REVISION, that > contains some info from the SCM system (e.g. a svn revision number, > a git sha1 hash).

There's been quite some prior discussion and examples of this in the list archives, but a perfect solution still would require some changes to Automake. Cheers, Ralf
