That should only be true when gcc provides the complete implementation. It's
clear this isn't true here. Libc is provided from something else, yet gcc
is deciding "it's knows best" and substituting it's own rules in between.
Basically according to the logic above any stdc89/99 defined function cannot
have any extentions without the user using -ffreestanding. BEcause otherwise
gcc (from what you say) could just completely inline libc from it's own
implementation and by god...assuming it actually used the one installed on
my system is my own fault for assuming something so likely....
