Hi Prateek,

(Just adding the library name to the subject line so the author might
notice. see http://www.boost.org/more/discussion_policy.htm#effective)

I am guessing there's a missing #include in the filesystem library and
that you may be able to work around it by adding

    #include <boost/type_traits/is_function.hpp>

before you #include any filesystem headers.  However, only Beman can
say for sure.
