+--------------------
+01e,29apr10,pad  Moved extern C statement after include statements.
+01d,21feb06,pes  Correct multiple definition protection for sched_param
+                 struct by using base/b_struct_sched_param.h.
+01c,11jan06,gls  added check that sched_param not already defined
+01b,05jan94,kdl	 removed include of private/schedP.h.
