Actually, using the cross-compilation feature seems more logical as his host-
cc obviously produces 32bit binaries. This also means that if he needs to link 
against libraries, etc., it is the same as compiling for a completely different 
architecture.

Having a 64bit system with a gcc default of -m32 is just a silly thing.
