* regex/engine.c (step): Drop Cygwin-specific definition.

Browse Source 
(NONCHAR): Better cast here to make the test work.  Move comment
	from step here.
	(matcher): Disable skipping initial string in multibyte case.
	* regex/regcomp.c (p_bracket): Don't simplify singleton in the invert
	case.
	(p_b_term): Handle early end of pattern after dash in bracket
	expression.
	(singleton): Don't ignore the wides just because there's already a
	singleton in the single byte chars.  Fix condition for a singleton
	wide accordingly.
	(findmust): Check for LC_CTYPE charset, rather than LC_COLLATE charset.
	* regex2.h (CHIN): Fix condition in the icase & invert case.
	(ISWORD): Fix wrong cast to unsigned char.
