[boost] filesystem\src\exception.cpp doesn't compile with UNICODE on VC7

When exception.cpp is compiled with Unicode defined in VC7 General Settings,
the following does not compile (LPTSTR is wchar_t*):

#       ifdef BOOST_WINDOWS
          LPVOID lpMsgBuf;
          ::FormatMessage(
              FORMAT_MESSAGE_ALLOCATE_BUFFER |
              FORMAT_MESSAGE_FROM_SYSTEM |
              FORMAT_MESSAGE_IGNORE_INSERTS,
              NULL,
              m_err,
              MAKELANGID(LANG_NEUTRAL, SUBLANG_DEFAULT), // Default language
              (LPTSTR) &lpMsgBuf,
              0,
              NULL
          );
          m_msg += static_cast<LPCTSTR>(lpMsgBuf);

It works with the following replacements:

FormatMessage -> FormatMessageA
LPTSTR -> LPSTR
LPCTSTR -> LPCSTR
