Subject: [PATCH] sched: check struct sched_param in spawn.h as well
On OS/2 kLIBC, struct sched_param is in spawn.h. So without this a
redefinition error occurs when sched.h is inclued by spawn.h.
* lib/sched.in.h: Include spawn.h on kLIBC.
* lib/sched_h.m4: Check struct sched_param in spawn.h as well.
