I think the original poster wanted info even on compilers he
didn't have installed.  Grepping through the config directory
of the gcc source tree as I suggested is messy, but will give
a pretty good idea of all the predefined symbols out there
(though it can't show any added by distributors, e.g. Montavista,
but not yet contributed to the main tree).
