I still get errors on the cast. I am not sure if this is a bug in gcc
2.96 or a real problem with the code. (either way it is a problem...)

static void do_once()
{
    once_callback* cb = reinterpret_cast<once_callback>(pthread_getspecific(key));
    (**cb)();
}

gives this compiler message:

once.cpp: In function `void do_once ()':
once.cpp:41: ISO C++ forbids casting between pointer-to-function and
pointer-to-object
once.cpp:41: cannot convert `void (*) ()' to `void (**) ()' in
initialization
