Update.
* locale/programs/ld-ctype.c (ctype_finish): Take all characters from
the input charset into account when generating the hash table.
(allocate_arrays): Correct setting default width. Not all empty slots
in the table are filled, only those not covert explicitly by the
locale description and in the charset.
* stdio-common/vfscanf.c: Make sure to always return WEOF and EOF for
wide character version.
For %C handling, test correct pointer variable for NULL.
* wcsmbs/wctob.c: Handle WEOF special.
* wcsmbs/wcwidth.h: 0xff in width array means invalid character.
* wctype/wctype.h: Protect gcc-isms with __extension__. Avoid
always-true test to avoid warning.
