more DEC Alpha diffs

[Guy Middleton <gamiddleton@math.uwaterloo.ca>]

long ints are 64 bits on an Alpha; this breaks the DNS parsing code
in transports/smtp.c.  There are probably other things that need fixing,
like using time_t instead of long for times, but this looks like the most
important one:
