The tow* functions use an included case conversion table which can be generated from Unicode data. The isw* functions use a character categories table (provided by categories.c) which can be generated from Unicode data. Delegation between current-locale and specific-locale-dependent functions was reverted towards the generic locale-dependent functions (*_l.c); this is however only relevant on systems with non-Unicode wide character locales, thus not on Cygwin.
