patch 9.1.2053: MS-Windows: May use wrong find command

Problem:  If another find.exe derived from findutils is installed on
          Windows, unintended behavior will occur. If MSYS2 is installed and
          prioritized over the system path, then find.exe derived from
          findutils will be launched during build, resulting in an
          unintended warning message.
Solution: Specify the absolute path including SYSTEMROOT to launch
          find.exe (Muraoka Taro)
