I assume you meant "'static'" instead of "nothing at all" - we couldn't replace 
INLINE with nothing at all, as that would cause duplicate function definitions.

I did try 'static' (actually, 'static ATTRIBUTE_UNUSED' to pacify gcc 
-Wunused-function) and found that it improved performance of 'make 
compile-always' by 8% on my old work desktop and by 6% on a newer machine, so I 
installed the attached patch. Using 'static' also shrank the text size of the 
executable by 4.5%, for what that's worth. 'static' also has the virtue of being 
simpler. At some point we can remove the EMACS_EXTERN_INLINE code as I expect it 
won't be needed.
