Dave,

Is there a chance that vc6_prj doesn't work with the changes made for the
new release? I got your release 10-31 and customarily wanted to compile 
its demo.dll (just checking that everything's ok :-), but got these
errors:

Since I see a lot of the (with me) infamous "const"s, I'm wondering
whether the vc6_prj code is perhaps not up to date.

Two other, minor points: vc6_prj.dsp is read-only, but I would guess that
most people need to do a bit of customization. And in the release version,
"warning D4025 : overriding '/Ot' with '/Os'" still shows up.

Some more info: I've just tried the new version with my own wrapping
project, and gotten the same kinds of errors, caused by code that worked
before (the TextRecordIterator parts are commented out; that very same
code works with your older version). Perhaps I'm missing some changes that
need to be made to the code for the new version?

Sorry to keep bugging you with this.
