Re: nptl 0.49

Hello Ulrich

First, big thanks about the pthread_cond improvements.

I have a remark about the use of FUTEX_REQUEUE

If the linux kernel is not FUTEX_REQUEUE aware, I think the syscall returns
ENOSYS and not EINVAL .

I suggest this change :

diff -u nptl/sysdeps/unix/sysv/linux/i386/i486/pthread_cond_signal.S
nptl-next/sysdeps/unix/sysv/linu
x/i386/i486/pthread_cond_signal.S
