Fails like this:

clang-linux.compile.c++.without-pth 
..\..\..\bin.v2\libs\filesystem\build\clang-linux-3.4.2\release\link-static\path.obj
..\..\..\libs\filesystem\src\path.cpp:36:11: fatal error: 
'windows_file_codecvt.hpp' file not found
# include "windows_file_codecvt.hpp"
          ^
1 error generated.

  "clang++" -c -x 
c++ -Wno-variadic-macros -Wno-c99-extensions -O3 -Wno-inline -Wall  -DBOOST_ALL_NO_LIB=1 
 -DBOOST_FILESYSTEM_STATIC_LINK=1 -DBOOST_SYSTEM_STATIC_LINK=1 -DNDEBUG -I"..\..\..\include" 
 -o 
"..\..\..\bin.v2\libs\filesystem\build\clang-linux-3.4.2\release\link-static\path.obj" 
"..\..\..\libs\filesystem\src\path.cpp"

Looks like a clang bug; the file is certainly there, in the same directory 
as path.cpp.
