GAS doesn't know anything about macros, conditional assembly etc., as it was developed only to assemble the stuff that comes out of a compiler. If you want to use macros and the like, you'll need to preprocess the file with 'gasp' (the GNU assembler preprocessor) and pipe the output of gasp into gas: gasp <options> <sourcefile> | as <options> I hope this helps.
