Yes, this is wrong, at least for w64. I used the w64 compiler by this and
it returns me for the probing code an result of -1.

The issue here is that msvcrt doesn't supports (for 32-bit and for 64-bit)
the %ll with specifier. For msvcrt80 (or so) they introduced it IIRC, but
this version isn't used by mingw as default runtime (because it isn't part
of the OS itself).
