Well if it uses x86 assembly, it won't work at all if you try to compile
it natively for amd64.  If it's just pure c/c++/whatever then there is
still the issue of pointer sizes (when people use the wrong type for
their pointers and hence assume pointers are 32bit).  Making software
compile on 64bit and work correctly is not trivial, although good
programing style should make it work in most cases, which of course
means an awful lot of programs don't work.
