[SV 58656] Fix mtime for large files on MS-Windows

In MSVC builds, 'stat' fails when called on files larger than
2GB.  Call '_stat64' instead to work around this.

* src/remake.c (STAT): Define to '_stat64' for MSVC builds.
(name_mtime) [WINDOWS32]: Use STAT instead of 'stat'.
Suggested by Makoto Kato <m_kato@ga2.so-net.ne.jp>.
