Unfortunately you still have to write yourself a traits class to do that, a 
simple wrapper that forwards calls onto c_regex_traits<char> where 
appropriate would do it.  Unfortunately the traits class design is going to 
change in the next release, which is why I'm nudging you towards the current 
cvs state, rather than the last release.
