Update.
* 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.
