Hmm ... it works properly on a 32-bit machine ...

There are a boatload of occurrences of this pattern in datetime.c:

                    integer_variable = strtol(field[i], &cp, 10);
                    if (errno == ERANGE)
                        return DTERR_FIELD_OVERFLOW;

which is okay if long and int are the same size, but not so much
otherwise.  Looks like we need to fix that.
