I can't answer for James, but I can tell you that few (if any) Ada compilers currently behave that way precisely because the Ada community as a *whole* does not accept compilers that do not adhere to the spec. In particular, there is a validation procedure that must be followed, which includes very extensive testing of the compiler against a large test suite designed to exercise as much of the Ada spec as possible. Many Ada users demand to see the conformance certificate before considering purchase of a compiler. I can't give you a good percentage of users that feel this way, but apparently it has been enough to discourage non-conformant compilers. Interestingly, I had heard (consider it a rumor, if you will) that at least one of these agencies has also developed conformance tests for C++, but not a single vendor has ever asked to use them. :-) >If you add difficult things into languages, two things happen. >They get implemented less, or sometimes they get implemented >incompletely. I'd say the experience of Ada's Distributed Programming annex bears this out. >We see this with C++: poor support for templates here and there, lack of >support for exception handling here and there. Apparently the bar for "difficult" in C++ is set a *lot* lower. :-) I'd just say that C++ community doesn't care nearly as much about portability as the Ada community (or perhaps they are more accustomed to not getting it). --- T.E.D. homepage - http://www.telepath.com/dennison/Ted/TED.html home email - mailto:dennison@telepath.com
