[PATCH,HURD] Permit to get a __sched_param structure from bits/sched.h

2010-09-01  Samuel Thibault  <>

        This aligns bits/sched.h onto sysdeps/unix/sysv/linux/bits/sched.h:
        define __sched_param instead of SCHED_* and sched_param when
	<bits/sched.h> is included with __need_schedparam defined.

        * bits/sched.h [__need_schedparam] (SCHED_OTHER, SCHED_FIFO, SCHED_RR,
        sched_param): do not define.

        [!__defined_schedparam && (__need_schedparam || _SCHED_H)]
        (__defined_schedparam): Define to 1.
	(__sched_param): New structure, identical to sched_param.
	(__need_schedparam): Undefine.
