gcc -E is your friend. :)

But so is sticking "#warning aardvark" into various headers to see
whether or not an #ifdef case is triggering (copy 'em to writeable space
and --bind mount the file back, yes bind mount works on individual
files), and of course the ever-popular:

gcc -E -dM  - < /dev/null

Which shows all the builtin #defines for your current compiler. (Works
on cross compilers too!)
