	* locale/C-ctype.c (_nl_C_LC_CTYPE_class32): Correct
	endianess for initialization value.

	* locale/lc-ctype.c (current): Add parameter for offset.
	(__ctype32_b, __ctype_width): Add initialization for these
	variables.

	width table are known to name table.
	(ctype_output): Correct handling of class and map name
	information and write out width information.
	(find_idx): Prepare for being called with NULL pointer as
	TABLE argument.  This means only allocate name entry.

	_PC_ASYNC_IO, _PC_PRIO_IO and _SC_CHARCLASS_NAME_MAX.

	* sysdeps/generic/stpncpy.c: Correct return value.

	* sysdeps/posix/fpathconf.c: Add handling of _PC_SYNC_IO,
	_PC_ASYNC_IO, and _PC_PRIO_IO.
