I am very concernced about something. The following code breaks with 2.4.1:

fcntl.ioctl(self.rtc_fd, RTC_RD_TIME, ...)

Where RTC_RD_TIME = 2149871625L

In Python 2.3 it is -2145095671.

Actually, this is supposed to be an unsigned int, and it was construced
with hex values and shifts.

Now, with the integer unification, how is ioctl() supposed to work? I
cannot figure out how to make it work in this case.

I suppose the best thing is to introduce an "unsignedint" type for this
purpose. As it is right now, I cannot use 2.4 at all.
