[boost] Doc error in regex?

I'm trying 1.31.0rc2.

    unsigned int flags = boost::match_default; 
    while(regex_search(start, end, what, re, flags)) { 

../Test/PlotComplex.cc:36: error: invalid conversion from `unsigned int' to
`
   boost::regex_constants::_match_flags'

But this is exactly what the example:
boost_1_31_0_rc2/libs/regex/doc/regex_search.html

shows.  Need to update the doc?
