According to AJ, we need to define _WIN64 on 64-bit archs. I've got a patch for that, but needs more work, since build fails on 64-bit RPC stuff.
d67275fed84e74072d202fc98c205f40c6d18b63 is in, but it needs much more work to get sparc64/powerpc64 to work. i doubt that we want that. Debian/sparc64 has a 32-bit userland anyway and you need -m64 to tell gcc you don't want to compile for 32-bit. i'm not sure about powerpc64, but as you ran accidently into that bug i guess it has a 64-bit userland.
PowerPC has a 64-bit userland, yeah (or at least that gcc farm machine does).
