I have mentioned this to Michael T. and said that I believe it to be a bug.
Perhaps the fact that other C++ compilers/translators accept this without
error will serve as some confirmation of my view.

Wow, that'd be neat, but like where does it say that this is correct
behavior?  Just because some Joe Compiler accepts it and "does the
right thing" with it doesn't *necessarily* mean that it's correct for
the language.  Can anyone quote chapter and verse about this subject?
(yes, i've been bitten by this same problem, and was annoyed to have to
declare two virtuals, but is it _correct_ C++?).
