True, but I *hate* warnings :-)...
Seriously, I was under the impression that these would potentially cause
problems when trying to instantiate/destroy an instance of one of these
classes. I've had a fair amount of bad luck with MS DLL-hell problems, and
I'm a bit leery of any type of warnings I get regarding them.
I haven't actually tried to run the code, yet so I don't know if it'll fail
or not, but if there is some workaround to get rid of the warnings (short of
pragma'ing them off), I'd appreciate it...
