Annexes C and D provide functionality in the real-time and system programming domain, which almost all user's of cross-compilers need. The other annexes are more "specialized," and as such, a critical mass of demand hasn't yet built up for them sufficient to entice other vendors to implement them. However, with the increasing interest in distributed component-based systems, even among the real-time crowd, I would expect at least the distributed annex to become more widely implemented. On the other hand, Ada/Corba is a viable alternative (e.g. ORBExpress/Ada from Objective Interface Systems), so that may have reduced the pressure for the distributed annex. I would also suspect that the safety-critical annex will be or is already supported by a number of vendors, even if they haven't validated against the Annex H tests. > > I was just wondering > > Robbi Sagris -- -Tucker Taft stt@averstar.com http://www.averstar.com/~stt/ Technical Director, Distributed IT Solutions (www.averstar.com/tools) AverStar (formerly Intermetrics, Inc.)
