Subject: [PATCH] 2008-06-05  Johannes Singler  <singler@ira.uka.de>

        * include/parallel/random_shuffle.h:
        (parallel_random_shuffle_drs) Get the actual number of
        threads after entering the parallel region. Indentation.
        * include/parallel/algo.h: (random_shuffle(begin, end))
        Add namespace qualification to avoid ambiguity.
