Comment:

 Hmm. Suppose that `gcc --print-file-name` would have printed a real file
 name, and instead the existence of `gmp` directory in basedir causes `gcc`
 to print the `gmp` in `basedir`. Wouldn't we now have lost information
 that `gcc --print-file-name` would have otherwise given? OTOH I guess
 there isn't really any way to get the correct information now (unless you
 remove `basedir`, I suppose)
