All in all I'm not sure to fully agree...

Actually, attribute((strong)) is a *recent* entry, only to support debug
mode, which I find really great! but not part of the core functionalities,
those mandated by the standard.

Otherwise, a bunch of builtin_expect (glibc also uses that, right?... and we
don't even agree that they are always so beneficial in our case), a bunch of
builtin_alloca, quite useful I admit, what else?
