Update.
1999-07-08 Andreas Schwab <schwab@suse.de> * 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. 1999-07-08 Andreas Schwab <schwab@suse.de> * manual/charset.texi: Fix typos.
