[boost] tokenizer in 1.27.0 compile errors when using with regex in MSVC6

This small program produces the errors below (fixed in 1.28???).  I had to
fully qualify the calls to ispunct in token_functions.hpp to make the
problem disappear.

#include "boost/regex.hpp"
#include "boost/tokenizer.hpp"

int main(int, char**) {
      boost::char_separator<char> c("."); 
      std::string s;
      boost::tokenizer<boost::char_separator<char> > tok(s,c);
      tok.begin();
      tok.end();
      return 1; 
}

d:\boost/token_functions.hpp(344) : error C2668: 'ispunct' : ambiguous call
to overloaded function
        d:\boost\1_27_0\dev\boost/token_functions.hpp(339) : while compiling
class-template member function 'bool __thiscall
boost::char_separator<char,struct std::char_traits<char> >::is_kept(char)
const'
