Just started using CVI 2010 so hadn't figured out it was still missing.
I suppose it isn't so much that bool itself is a compelling deficiency in CVI, the problem seems to me to be more so that you have to keep track of a confusing medley of what's implemented and what's not. For example, using a good reference such as H&S for C, you're going to be confused all the time because the reference generally is written to C99, some of which you'll be able to use in CVI and some you won't.
