Use fseeko64/ftello64 for mingw32. It turns out i686-pc-mingw32 does define these functions, and they are always available (unlike _fseeki64/_ftelli64). This means we can build and link without requiring i686-w64-mingw32. The resulting binary still doesn't run in wine for me, but that may be a personal problem.
