// The shell guys insist that Wordpad call GetOpenFileName with the newest
// OPENFILENAME structure but MFC doesn't support it.  MFC also needs to be
// built with _WIN32_WINNT set to 0x0400 so Wordpad can't even see the new
// structure.  Since the shell guys won't change the way they define the
// structure so that Wordpad can see both versions, it has to be snapshotted
// here.
