* sysdeps/mach/sched_yield.c: New file.

2000-03-13  Roland McGrath  <roland@baalperazim.frob.com>

	* sysdeps/generic/lockfile.c: Include <stdio.h>
	(_IO_flockfile, _IO_funlockfile, _IO_ftrylockfile): #undef these in
	case <libio.h> defined them.
	(__flockfile, __funlockfile, __ftrylockfile): Functions renamed
	from __internal_*.
	(flockfile, _IO_flockfile, funlockfile, _IO_funlockfile,
	ftrylockfile, _IO_ftrylockfile): Fix aliases accordingly.

	* sysdeps/generic/bits/stdio-lock.h (_IO_lock_initializer): Use ...
	for more pleasing parse error.

	* elf/Makefile: Add rules to compile and run constload1 test.
