Yes, that is what I meant. Either you emit relocations into the ELF file, and rely on the dynamic loader to interpret them, or you compile a procedure to do the relocations and call it as an init function. Wip-rtl does the latter, because that way we can also do one-time initializations like string->symbol, string->number, etc. Andy -- http://wingolog.org/
