Unfortunately, Dejanews does not give me that option, so its a bit difficult
to do. I'll hack it my posting this w/ "send me a copy", and forwarding the
copy to you.

I noticed. What I'd like to know is what it *is* doing to optimize things? The
thing that got me curious was that I never got any "optimized away" messages
when I tried to look at things in the debugger. I don't know much about i386
instructions, but I do know that the Pentium has a base of RISC instructions.
You have to wonder about the efficiency of any compiler that doesn't optimize
variables away to registers on a RISC processor.

When I called tech support, he said he never had a question about
optimizations before. I found that rather shocking, but if its true then you
are obviously right to concentrate on other things.

I suppose the typical response to slow code on a Wintel platform is "buy a
faster box".

Cool. I was getting jealous. :-)

I'll look into it. Thanks.
