Okay, will do.

I think that new type for the var should be Elf_Addr, if any. Look at its use. In fact this is an ABI issue.

Practically Elf_Addr has the same representation as size_t on all supported platforms, but this is not strictly required.

I would do a follow-up commit removing space before '('. Or you might add it to this change.
