* 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.
