	* include/bits/regex.h (__compile_nfa<>(), basic_regex<>::basic_regex(),
	basic_regex<>::assign()): Change __compile_nfa to accept
	const _CharT* only.
	* include/bits/regex_compiler.h: Change _Compiler's template
	argument from <_FwdIter, _TraitsT> to <_TraitsT>.

	* include/bits/regex_compiler.h: Change _ScannerT into char-type
	templated.
	* include/bits/regex_scanner.h (_Scanner<>::_Scanner()): Separate
	_ScannerBase from _Scanner; Change _Scanner's template argument from
	_FwdIter to _CharT. Avoid use of std::map and std::set by using arrays
	instead.
