+       Make the 'sched' module work on platforms where <sched.h> exists but
+       is incomplete (such as Haiku).
+       * lib/sched.in.h; Include the system's <sched.h> if it exists.
+       (SCHED_FIFO, SCHED_RR, SCHED_OTHER): New macros.
+       * m4/sched_h.m4 (gl_SCHED_H): Test whether <sched.h> exists and also
+       defines SCHED_FIFO, SCHED_RR, SCHED_OTHER. Set HAVE_SCHED_H,
+       HAVE_STRUCT_SCHED_PARAM.
+       * modules/sched (Depends-on): Add include_next.
+       (Makefile.am): Substitute HAVE_SCHED_H, INCLUDE_NEXT,
+       PRAGMA_SYSTEM_HEADER, NEXT_SCHED_H, HAVE_STRUCT_SCHED_PARAM.
+       * doc/posix-headers/sched.texi: Document the issue.
