        * gthread-posix.c, gthread-solaris.c: Changed the prototype of
        thread_create and thread_self to return the system thread into
        provided memory instead of a return value. This is necessary, as
        HPUX has a pthread_t, that is bigger than the biggest integral
        type there. Made some more functions static.

        * gthread-posix.c: Small fixes for DCE threads: Detaching has to
        be done after thread creation for DCE.
