But as static destructors don't seem to fire under native Win32, we
should use theLog.

As for the patch, it's good :}. I've designed what I need to do to
libgetOpt++ to make gui help happen. We need a strategy for
ParameterUsage, with a builtin strategy that does the current behaviour.
We then provide a new strategy, and that will call back a class of ours
with each parameter. It's pretty trivial, but I've overrun my time
budget for cygwin already today, so .. another day. We need a strategy
because a stream isn't structured enough for possible GUI help displays.

If you want to take a crack at this, feel free :].

I will do this this week sometime though.

Rob
