Which is probably not really in line with gnu coding standards
(standards.info end of "Syntactic Conventions" node).  But I guess any
application might do it.

That was ceval/deval() local variables on gcc 4 last time I hit that.
-O1 may be better, or just on eval.c at least.

I suspect extern inline is what you want, static inline might end up
with a copy of the code in every file, under -O0 at least.  But extern
inline is even more of a gcc-ism, if you're worried about the
commercial compilers.
