	[BZ #730]
	* stdio-common/tst-fmemopen2.c: Include string.h.
2005-01-05  Ulrich Drepper  <drepper@redhat.com>

	[BZ #730]
	* libio/iofopncook.c (_IO_cookie_seekoff): Define.  Mark offset as
	invalid to disable optimizations in fileops which won't work here.
	(_IO_cookie_jumps): Use it.
	(_IO_old_cookie_jumps): Likewise.
	* libio/fmemopen.c (fmemopen_seek): Result must be returned in *P,
	not the return value.
	* stdio-common/Makefile (tests): Add tst-fmemopen2.
	* stdio-common/tst-fmemopen2.c: New file.
