Found out the answer here: http://dslweb.nwnexus.com/~ast/dload/guicon.htm

DWORD ret = AttachConsole(-1);
if (ret != 0) {
   HANDLE lStdHandle = GetStdHandle(STD_OUTPUT_HANDLE);
   int hConHandle = _open_osfhandle((intptr_t)lStdHandle, 0);
   FILE* fp = _fdopen( hConHandle, "w" );
   *stdout = *fp;
}
