If the patch makes any difference, this suggests that __GXX_WEAK__ is defined on AIX, but that we can't rely on a weak undefined symbol for this purpose. Back to the drawing board... I'm reverting this for now. Maybe we should narrow it down to targets in which weak undefined symbols are available with the expected semantics, and where the symbol is known to have ever been defined in libc. On it... Or maybe a weak definition (or weak alias to a definition) in that file would enable us to test whether the weak definition was preempted, and use it if so. Or even move the fallback definition into the weak symbol.
