What are our options here wrt Alpha _and_ i386? If we stick with what we have for 3.0 to avoid a last minute change that might destabilize the i386 release, we need to at least release a snapshot of FreeBSD/Alpha at the same time and that must contain the tools to support building the world. The alpha Alpha 8-) release can contain XFree86 libs and clients built on a later compiler if required, since we don't build those with the world. I'd like to see the compiler issue reviewed after 3.0 in the light of the release of egcs and the poor C++ support that gcc 2.7.X has. -- John Birrell - jb@cimlogic.com.au; jb@freebsd.org http://www.cimlogic.com.au/ CIMlogic Pty Ltd, GPO Box 117A, Melbourne Vic 3001, Australia +61 418 353 137 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
