----------------------------------------------------------+-----------------
 Boost 1.50, MS Visual Studio 2010. I find that if I attempt to use the +
 operator on a path::iterator, I get a compiler error saying that the
 method "advance" is not part of path::iterator. If I comment out my use of
 this operator, and instead use only ++, then everything compiles.

 Here are the details from the compiler:
 {{{

 member of 'boost::filesystem::path::iterator'
