The n3376 standard specified the following constructor:

...
explicit basic_regex(const charT* p, flag_type f = regex_constants::ECMAScript);
basic_regex(const charT* p, size_t len, flag_type f =
regex_constants::ECMAScript);
...

So flag_type shall not be the same as size_t. I don't know if when I
switch flag_type from unsigned int to, say, unsigned short, conflicts
will appear in 16bit archtectures.
