Is there a way to run the GCC preprocessor, but only for user-defined macros?

I have a few one-liners and some #ifdef, etc. conditionals, and I want to see what my code looks like when just those are expanded.

As it is, the includes get expanded, my fprintf(stderr)s turn into fprintf(((__getreeent())->_stderr), etc.

c gcc macros c-preprocessor
