I believe that the version 3 filesystem headers which use std::mbstate_t 
need to include cwchar, but that they do not. This gives an error when I 
compile using Comeau with a VC9 backend, although compiling directly 
with VC9 is OK. This probably happens because of the assumption in 
filesystem that cwchar is included by some other C++ header, but rather 
than make such an assumption it would be better if cwchar were included 
directly by any header file which uses std::mbstate_t.
