My point was just that there's nothing that forces every compiler to make "-I<dir>" the way to set the include path. It happens to be that way for a few popular ones like icc because people generally just do what GCC does. But nothing stops someone from making a compiler where it uses lowercase i, for instance. These options HAVE to be compiler specific. > >> Consider, though, using cl.exe in an msys environment.

I'm trying to make that work, actually. It's very hard. _______________________________________________ Autoconf mailing list Autoconf@xxxxxxx https://lists.gnu.org/mailman/listinfo/autoconf
