GPL 3 is a bit hard on the non-GPL systems (i.e. harder than > GPL 2). There are several things people can do to mitigate the issues here. They can work to make it easier to completely replace the base compiler with a port. It seems not unlikely that FreeBSD distributions like PC-BSD will eventually do this. They can track GCC enhancements and when those enhancements are actually compelling make a case for an upgrade. We haven't closed the door on that possibility, but the bar is quite high given the number of FreeBSD customers who have a "no GPLv3 source in house, no exceptions!" policy. They can work on LLVM support and integration. Apple is putting a lot of effort into both llvm-gcc and clang. From the outside, it looks like they consider that their future. As such, it may well be ours. -- Brooks --/9DWx/yDrRhgMJTb Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.8 (FreeBSD) iD8DBQFJLXgTXY6L6fI4GtQRAisOAJ0REwL5o3cQseRNQLHa2JMM9RVnrACfYZFe f5ZD+S7toIMyZ6UrnCAtqoI= =da1t -----END PGP SIGNATURE----- --/9DWx/yDrRhgMJTb--
