unix assembly programming

[Mohan <manmshuk%gmail.com@localhost>]

is it common to use m4 with gas? are there examples
i can learn from or just general resources for unix asm
programming?

so far, i've found a mailing list called linux-assembly
and read a few little programs hosted on sourceforge.
i'm just a beginner trying to get a grip on the toolchain
internals. i also learned that gas dropped gasp in favor
of CPP and gas's internal macros, so i thought why not
look at m4. cuz i heard fasm has more expressive
macros.
