Yes but what i was referring to is the test the checks for NPTL vs Linux
threads. That test is/was broken and i don't remember off hand if they
by accident (using gcc) got it right or not on a NPTL system.
I now for certain that using non GCC compilers the test fails horribly
and gets it completely wrong. (Unless they have fixed it since i tried
on 1.0 and early 1.1 and 1.2)
I did send a patch but i have yet to see it being included.
