Getting GCC to tell me what it sees?

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Is there a way to get GCC to show all the information relevant to building? IOW, the include path it will use, the places it will look for libraries, etc? I'm not really sure what I'm asking, but I'll know it when I see it.
