+
+	* locale/localeinfo.h (LIMAGIC): Update value for LC_CTYPE.
+	* locale/langinfo.h: Define _NL_CTYPE_NONASCII_CASE.
+	* locale/C-ctype.c (_nl_C_LC_CTYPE): Add initializer for
+	_NL_CTYPE_NONASCII_CASE.
+	* locale/programs/ld-ctype.c (locale_ctype_t): Add nonascii_case
+	field.
+	(ctype_finish): Check whether there are any 8-bit characters outside
+	the range ASCII has or whether the mapping isn't the same as for
+	ASCII (±0x20).  Set nonascii_case appropriately.
+	(ctype_output): Add output handler for nonascii_case.
