[Boost-users] Counting matches with Regex V4

<Using VC7.0>

I'm converting to V4 of Regex, and I thought I might be able to count regex
matches using this snippet:

boost::regex e;
std::string::const_iterator first, last;
//Initialize first, last
boost::sregex_iterator itBegin(first, last, e)
boost::sregex_iterator itEnd;
ptrdiff_t pd = std::distance(itBegin, itEnd);

I get these errors:

xutility(312) : error C2665: 'std::_Iter_cat' : none of the 12 overloads
can convert parameter 1 from type 'boost::sregex_iterator'
        xutility(127): could be 'std::_Int_iterator_tag std::
_Iter_cat(std::_Bool)'
        xutility(133): or       'std::_Int_iterator_tag std::
_Iter_cat(char)'
        xutility(139): or       'std::_Int_iterator_tag std::

        xutility(145): or       'std::_Int_iterator_tag std::

        xutility(151): or       'std::_Int_iterator_tag std::

        xutility(157): or       'std::_Int_iterator_tag std::

        xutility(194): or       'std::_Int_iterator_tag std::

        while trying to match the argument list '(boost::sregex_iterator)'
        myfile.h(47) : see reference to function template instantiation
'ptrdiff_t std::distance(_InIt,boost::sregex_iterator)' being compiled
        with
        [
            _InIt=boost::sregex_iterator
        ]

Anyone have any thoughts?  Is it a VC7.0 issue?  Is there a better or
different way of doing the same thing?
