I think he was refering to gcc's gthreads implementation ?. not sure if it was ever used for much else than the objc compiler, it does not support threading in C++ as far as i know.
gthread is used by libstdc++ to implement standard threading facilities [1] and by various libraries for their own use [2].
But really, you reminded me about Objective-C. Those `__gthread_objc_*` functions are still left unimplemented. Maybe I should add them some time later.
