	Ok, the above patch does indeed solve the problem. And this
appears to be the only place AbsoluteTime needs to be copied to a time_t
variable. I can't find any other casts of AbsoluteTime to time_t, and
with this patch applied all regression tests pass just fine (save for
geometry of course with its standard off by one in nth decimal place
	Additionally, I do not see how this patch could break other
platforms. At worst, it is a minor slow down that might even be optimized
out by some compiliers when they see that sizeof(AbsoluteTime) ==
sizeof(time_t). I will defer to the core developers on how you want to
apply this patch to the source tree (i.e. with #ifdef alpha && linux or as
above). Though probably best to add a bit of a comment beside it so
someone does not remove it later thinking they are "optimizing" the code.
	At this point, Linux/Alpha should actually run out of the box! Let
me know when this patch is applied (in what ever form it ends up as) and I
will download a new snapshot and test it.
