[Adrian Bunk]

"extern inline" doesn't make much sense.

Yes it does.  "extern inline" tells gcc not to fall back to out of
line version if it can't inline the function.  These functions *must*
by inlined, or they'll break horribly on Sparc, at least.

For any non-ancient gcc and !alpha, we are already telling gcc via 
__attribute__((always_inline)) that it should abort compilation if it 
can't inline the function.

The problem is that "extern inline" gives warnings with 
-Wmissing-prototypes, and I want to add this flag to the CFLAGS since it 
helps us to avoid a class of nasty runtime errors.
