The reason is that reg.c REG_DWORD handling code uses strtolW() for
string conversion[1]. If the value greater than LONG_MAX, strtolW()
returns LONG_MAX, so this test doesn't pass if sizeof(long) == 4.

I'm not sure all wine platform use LP64 architecture then, so I
introduce above quirks. In retrospect, 0xdeadbeefU < LONG_MAX is
easier to read, I think.
