I'd suggest to ask the maintainer of the gcc port how this is supposed to work, i.e. what's the right way to actually use the C++ programs built with the gcc port. So far I don't see any gmp or sparc64 specific problem here and building gmp with the gcc44 port on amd64 and ia64 should result in the same problem. Marius
