-Before including anything, we need to fix up MinGW's MSVCRT defines.
-
-MinGW's <sys/stat.h> requires __MSVCRT_VERSION__ >= 0x0601 to define
-_wstat64(). This is fine for the MinGW distributed with GHC, which sets
-__MSVCRT_VERSION__ = 0x0700, but fails for the Haskell Platform because
-its MinGW sets __MSVCRT_VERSION__ = 0x0600.
-
-Therefore, we include <_mingw.h> first and bump its MSVCRT if necessary.
