This is the last one from me on this topic, I promise.

No, the obvious reason for the question is that he simply did a normal
update and lost the g++ functionality that he had previously had.

In a way, it was installed.  The problem here is that the previous gcc
pacakge contained all of the gcc, gcc-g++, gcc-g77, etc. functionality.
Relying on the release announcement for this information seems like
asking for this kind of problem report to me.

Additionally, when once chooses all->install to just get everything, the
gcc-core and gcc-testsuite source packages are *always* re-installed.

If the old gcc package had become an empty placeholder dependening on
the new packages that replaced its functionality, this question would not
have been posted.  Further more, if there were empty binary packages for
the source only ones (gcc-core and gcc-testsuite), my second observation
would not occur.

<\end rant>

It seems to me that the gcc package and the gcc-core packaga are backward
(at least in FSF normal terms).

I wish I knew how to fix it now, but it seems too late to reverse the
package meanings, or fix the dependencies.  Suggestions are more than
welcome.  IMHO, the empty binary packages for gcc and gcc-core would
still be "a good thing".
