klibc is written in the same style as the Linux kernel, which is
currently GNU style for inlining; I am not going to support more than
one style for reasons of maintainability.

Furthermore, your patch actually *removes* a fix by which we enforce
GNU-style even if it is not the default, so it's in fact doubly wrong.
