Re: C++ parser for diagnostics

Thanks very much for that response.

I was thinking of this code beyond just exception handling, but the minidump
stuff sounds neat so we'll look into that too.

I guess the _penter logic can't determine the file/line/funcname of the
function being entered? I'll check it out though.

I was more thinking of a source level preprocessor to addresss this
requirement.

Thanks for the ideas though,
Dave
