Are you saying that if a Cygwin Make uses DOS style file names with drive letters, it also expects the PATH-style directory lists to use a semi-colon as a separator? I don't think I'd expect that. I think PATH-style lists should always use Unix-style file named in the Cygwin Make. DOS-style file names should only be supported in targets and commands. > > It probably would, if you do a clean job, but frankly I'm not sure it's > > worth your while.

I know about MSYS, but building an MSYS version of Make is already a special procedure. So I don't see why you should worry about that. _______________________________________________ Bug-make mailing list Bug-make@gnu.org https://lists.gnu.org/mailman/listinfo/bug-make
