* libio/oldfileops.c (_IO_old_file_xsputn): Fix last patch.
	Return EOF not 0.

	* sysdeps/unix/sysv/linux/readonly-area.c (__readonly_area): Also
	allow EACCES errors when opening /rpco for now.

	* wctype/wcfuncs.c: Don't use expensive wide char lookups in isw*
	functions if character is in ASCII range.
	* wctype/wcfuncs_l.c: Likewise.
