I recently read a discussion on this topic on the GCC mailing-list
(requiring an ANSI C compiler to bootstrap GCC) and it appears that the only
blocker is H-P, which still bundles a K&R system compiler with the newest
versions of HPUX. You have to give them some additional bucks to get an ANSI
C compliant compiler.

Yes, it would probably never hurt to learn from GCC about portability.
