GCC's statement expression extension

[Richard Kenner]

    Your opinions are valuable.  Although I think you may not fully
    understand the C++ user base.  

I'm talking about *C* not C++. As you point out, I know nothing about the
latter user base.

    On the other hand, the arguments Michael makes apply to almost any
    extension, and I do not agree, by any means, that we must preserve all
    extensions for all time.  The same argument justifies preserving many
    bugs; every time we issue an error that we did not before, we break
    programs.

Sure, and that is indeed a problem.  For example, the latest sources cannot
compile the GCC that has part of SPEC due to a new error message.

With as large a user base as we have, we cannot afford to ignore these issues
and if we try to, we'll surely hear about it.
