I would also note that the use of a signed integer as the type of the
gid_t python argument is wrong, it should be an unsigned integer at
least for linux, and we should determine that the parameter was not
specified another way.

But I also can't think of a good reason for gid value > INT_MAX on an
AD DC, so this should be academic.
