That's a poor test of any other compiler, or of what's possible, then.
MS used the setjmp/longjmp approach to EH with that compiler, for
compatibility with "structured exceptions." The 64-bit compiler has a
"real" EH implementation ;-)
One more thing to note about the case of terminating graph algorithms
with exceptions: these algorithms have *lots* of hooks for each
iteration of the process, each of which might need to terminate the
so that can add up to quite a few tests for each iteration of the inner
loop, which can be avoided if EH is used.
