Yes I saw them. However pease look at the if else endif guards in the  
header.
extern inline is just supposed to guarantee that a copy
of the function will be spawn out to an .o file when it's seen. Right?
The variant in toplev.c will be of course generated as well. And then
it's just link order roulette which one of them will be used...
