I cross-compiled two "fat" GCCs, and then used the local
GCC/G++/GDC to build the rest of the phobos library with.

Now, the only thing that remains to be tested here is :
Does It Work ? :-) (as I don't have any Intel Mac here)


Put a new package up on SourceForge to find out, I guess ?
(there's the regular GDC support files, beyond the above)

PS. The "hello x86 world" disassembly looked quite alright...
