Mmm, but at the moment it's entirely fine to pass both compilers
the same flags, and moreover we actually pass all these flags
to the compiler without checking if it's gcc or not; we just
ask if the compiler will run OK with the flag passed. (I'm not
even sure how you'd determine whether your compiler was gcc
or clang or gcc-llvm or whatever...)

I agree that those bits of configure could be cleaner.
