Hi, I'm trying to understand the motivation for renaming configure.in to configure.ac. If I remember correctly it was related to the fact that ./config.status or whoever else processes .in files. I goggled but was unable to find it. If this is the motivation and no `effects' depend on the file name, I think it might not be worth to rename configure.in files in old projects, because when working with CVS (or other VCS that do not handle renaming well) and when having to maintain old branches. When renaming such a file, after cvs update make will fail for the developers (and they need to rerun autoreconf and configure). Is the renaming configure.in to configure.ac cosmetic only and is it safe to keep configure.in in old projects/branches? oki, Steffen _______________________________________________ Autoconf mailing list Autoconf@xxxxxxx http://lists.gnu.org/mailman/listinfo/autoconf
