Hmm - I thought I was. Actually I'm not doing the testing. I'm just relying
on the table of test results which refers to compiler "CW" So I don't really
know what version it is. CWPro9 fails export and wide char tests on my
machine when built for debug and CWPro8 fails tests on Rene's machine and he
builds for release. So I just assumed the CW referred to some previous
version. Since it was passing I never had to find out what it really was.

I never set out to make CW pass. It just did. I have spent time with CWPro
as Rene expressed an interest and has been willing to help. The same goes
for Borland where Pavel Vozenilek invested most of the effort. I wouldn't
have done either of these were it not for this. I should say they did take
a lot more effort than I originally anticipated - but then that applies to
just about everything I do.

Generally, I would agree that it makes no sense to spend effort to
accommodate a compiler for which an upgrade is available. I wonder if
having them in our test matrix creates a subtle pressure on developers to do
the otherwise un-necessary work. It sort of plays on the obsessive aspect
of the typical software developer personality.
