I would add: 6) change strcpy to string_copy so gcc doesn't think it knows what the function does 7) code RELOC etc. in assembly, which would let us get rid of the offset = reloc_offset(); at the beginning of each function which uses RELOC. Maybe 7 is the way to go, at least it will shut the bush-lawyers up.
