IMHO as long as there are people using gcc 3 (and that seems to be the case
considering this) it does make sense to report such things. Its certainly
not nearly as important as bugs in latest gcc but still, there might be
people who are forced to use it who might be interrested in fixing or
who might just like to keep track of bugs in gcc 3
but as said its not that important ...

Awnsering whenever a program halts or runs forever is
On a turing machine, in general impossible (turings halting problem).
On any real computer, always possible as a real computer has a finite number
of states N, and will either halt in less than N cycles or never halt.
