8634	boost/filesystem/path.hpp is not self-sufficient	Valentin Shtronda <valiko.ua@…>	Beman Dawes	"The following code is compiled under VC2012:

{{{
#include <boost/filesystem.hpp>
boost::filesystem::path p(""file.txt"");
size_t hash = boost::filesystem::hash_value(p);
}}}

but gives link error:

{{{
error LNK2019: unresolved external symbol ""void __cdecl boost::hash_combine<wchar_t>(unsigned int &,wchar_t const &)"" (??$hash_combine@_W@boost@@YAXAAIAB_W@Z) referenced in function ""unsigned int __cdecl boost::filesystem::hash_value(class boost::filesystem::path const &)"" (?hash_value@filesystem@boost@@YAIABVpath@12@@Z)
}}}

I fixed it by replacing

{{{
#include <boost/functional/hash_fwd.hpp>
}}}

with

{{{
#include <boost/functional/hash.hpp>
}}}"	Bugs	new	To Be Determined	filesystem	Boost 1.53.0	Problem
