With a little more work, you can do the patch in 'luaconf.h', which is
an "official" place to do patchesj by only adding these lines in its
"Local configuration" section:

  #if defined(liolib_c) && defined(__MINGW32__)
  #include <sys/types.h>

  #define l_fseek(f,o,w) fseeko(f,o,w)
  #define l_ftell(f) ftello(f)
  #define l_seeknum off_t
  #endif
