WPATH_FORCE() not defined on windows when compiling with msvc.

[MiguelAmaro]

I'm trying to compile on Windows (x64) using the make.bat file found in .\mecab\mecab\src\ and had the following errors occur. I noticed that the WPATH(path) gets preprocessed to WPATH_FORCE(path) which is never defined. Is there a reason for this?
compiler version: MSVC 14.32.31326
