I'm aware of the quirkiness and other issues of vector<bool> which is
why I actually posted this. Additionally, it can cause performance
issues.

For the most part just about everything will translate to the STL
types. The reason for RogueWave is also the threadsafeness where the
Linux native implementation is not threadsafe. I've reasonably
experience with using the STL string, vector, map and set types.
