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.
