No -- it means that fixing *non-regressions* is almost never a
priority for a release.

That doesn't mean "C++ isn't supported".

The whole point is to *support* our C++ user base by eliminating
regressions, thereby providing a consistent, improving compiler.
That's exactly why I don't want to introduce risk -- each new patch
makes it harder to fulfill that basic contract: that GCC 3.0 be as
good as GCC 2.95 so that people can upgrade as easily as possible.
