In addition to the automatic changes, also do the following, needed due to recent Gnulib changes. * admin/merge-gnulib (AVOIDED_MODULES): Add btoc32, c32_apply_type_test, c32_get_type_test, c32isalnum, c32rtomb, c32tolower, c32toupper, localeinfo, mbrtoc32-regular. Remove btowc, iswctype, mbrtowc, wcrtomb, wctype, wctype-h. Also remove iswblank, iswdigit, iswxdigit, locale-h, raise, stdarg-h, some of which perhaps could have been removed earlier. * configure.ac (_REGEX_AVOID_UCHAR_H): New macro.
