Well, I had originally thought that you'd want to support easier cross-compilation from the x86, but now that I really think about it I guess I can see as how you'd have more SPARC hardware lying around to bootstrap from than you would x86 hardware. :-) However, for the medium term, it still might be a good idea to to see how NetBSD handles the problem of a single compiler source tree which can be built for different architectures. If you want an account on my NetBSD/ALPHA box, just let me know. :) [Might not be a bad idea in any case since you could see how they've addressed many of the 64 bit issues there]/ Jordan
