Arguable UI bug

[seebs at plethora dot net (Peter Seebach)]

While this isn't actually a "bug" in the canonical sense, it confuses users
with enough regularity to suggest that a change is in order.

When gcc cannot allocate more memory, it claims that "virtual memory is
exhausted".  This carries the unfortunate implication that the host
environment has no more swap space, but in many cases, it refers to software
limits.  A rewording of the message might help people understand it better.
Possibly something like
	can't allocate any more memory
would be less confusing.
