[boost] regex: problem using boost::reg_expression<unsigned short>

Backhround:
    On Solaris, wchar_t is 4 bytes(int), not 2 bytes as on 
    windows and on Linux. In our app, we want to work with
    2-byte-wide strings on any platform, so we define

       typedef basic_string<unsigned char> unicode_string;

    , which is different from basic_string<wchar_t>,
    but this works perfectly good with STL. So far, so good.
    
Problem:

    With boost regex, when I'm trying to use this regex 
    compatible with basic_string<unsigned char>:

typedef boost::reg_expression<unsigned short,
   regex_traits<unsigned short>, BOOST_DEFAULT_ALLOCATOR( 
   unsigned short)> re_type;

    ,I get million of compile errors about missing traits etc.

Question:
Q: In order to use boost::reg_expression<unsigned short,..> on the
platform where
'wchar_t' is not 'unsigned short', what do I need to do ?
