The _EXTERN_INLINE macros aren't there to protect against non-gcc;
they are there so that we can compile a version of the function that
will be a non-inline regular function.  

This is important for three reasons:

1) Users cannot be assumed to be always using C; we should support
   users who want to call out to the library from other languages or
   other language processors, not just old broken C compilers;

2) Users must be allowed to do things like take the address of the
   library functions which require an external version to exist;

3) GCC does not promise to inline every call to a function declared
   inline, but is allowed to generate a regular call if that looks
   best.
