commit b80ec5369182532a06bf4972ff274bc152d5eda6
Author: Carlos O'Donell <carlos@systemhalted.org>
Date:   Wed Nov 25 18:18:56 2009 -0500

    Add correct aligment to pthread_*_t structures.
    
    In the switch to NPTL the pthrad_mutex_t, pthread_cond_t,
    and pthread_rwlock_t structures were made binary compatible
    with the Linuxthread versions. However, their aligment when
    embedded in other structures was changed. When rebuilding
    libstdc++ this was detected, and the following changes return
    the structures to their original Linuxthreads alignments.

    	Use correct alignment for pthread_mutex_t, pthread_cond_t,
    	and pthread_rwlock_t.

    Avoid warnings when including atomic.h.
    
    Cast oldval to the same type as ret to avoid warnings when
    including atomic.h.
