I fail to see how gcc is the relevant point here given that there is 
equivalent definitions available from multiple compiler vendors.

Also, 'static inline' *is* C99 conforming as far as I can see? The problem 
with it is that some compilers may warn if the function isn't used in the same 
translation unit. Thats doesn't make not using a function non standard-
conforming though.

No, it won't improve that. But neither will the contrary.
