So, ok, there are a few cases where you don't want to subtract the segment
base:
1. Direct jmp, jcc, or call (but not ljmp or lcall);
2. If you for some reason implement PIC, then a PIC offset.
gcc already have to treat these specially; I find it hard to believe it would
be a significant burden to handle these subcases. However, if it *is* a problem
I think it can be resolved; it is mostly a matter of parsing.
