Patch from Christian Krause:

    I found a problem in uClibc in libpthread/linuxthres/condvar.c:

    pthread_cond_timedwait never uses rt singals

    uClibc has two implementations of pthread_cond_timewait -
    pthread_cond_timedwait_relative_old using the "normal" signals and
    pthread_cond_timedwait_relative_new usign the rt signals
    (for kernels >= 2.2).

    The function pointer pthread_cond_tw_rel is initialised with the old
    function. In "__pthread_init_condvar(int)" this pointer is set to the new
    function using rt signals, but "__pthread_init_condvar" is never called in
    the uClibc.

    The following patch solves this issue, so that __pthread_init_condvars
    is called and the function pointer is always initialised with the correct
    function.

    regards,
    christian
