Roland McGrath 1b67abbbfd 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.
