Sorry, I didn't go much further. Now it breaks in the following code:
bool parse_counter_placeholder(path_string_type::const_iterator& it,
path_string_type::const_iterator end, unsigned int& width)
{
return qi::parse
(
it, end,
(
qi::uint_[phoenix::ref(width) = qi::_1_type()]
)
);
}
The error is:

struct or class type
path_string_type is a flavour of std::basic_string. The code looks pretty much
like what is in Boost.Spirit docs. Am I doing something wrong?
