	* libio/iofopncook.c (fopencookie): Set _fileno to -2.

	* libio/libioP.h (_IO_file_is_open): Only check for -1, not all
	negative numbers.

	* libio/fileops.c (_IO_new_file_close_it): Set _fileno to -1, not
	EOF.
	* libio/oldfileops.c (_IO_old_file_close_it): Likewise.

1999-07-08  Andreas Schwab  <schwab@suse.de>

	* stdio-common/vfprintf.c (buffered_vfprintf): Initialize _mode.

1999-07-08  Andreas Schwab  <schwab@suse.de>

	* libio/fileno.c: Return -1 instead of EOF and set errno if the
	stream is not a real file stream.
