Yes, includes for native programs will may cause trouble -- but you can't use -nostdinc (as that would take away that feature from a user), which is why this needs to be in the gcc specs. I don't have a script as I just copied include directories from a i386 system. But a script would be better. This script was an initial stab at proper -m32 support and needs more work. I will be happy to work with you or anyone else to make this happen. _______________________________________________ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "freebsd-hackers-unsubscr...@freebsd.org"
