Indeed, this is confusing.
The gcc-3.4 source package builds libstdc++6-{dbg,dev,pic} which
depend on libstdc++6 (>= 3.4.6-5).
The gcc-4.1 source package builds libstdc++6-4.1-{dbg,dev,pic} which
depend on libstdc++6 (>= 4.1.1-19).
The current version of libstdc++6 satisfies both dependencies, and
this is proably wrong.
Stephan, the workaround for now is to install
libstdc++6-4.1-{dbg,dev,pic}, and remove libstdc++6-{dbg,dev,pic}.
Proposed solution 1:
1) Do not build libstdc++6-{dbg,dev,pic} from gcc-3.4 anymore.
2) In gcc-4.1, change libstdc++6-4.1-{dbg,dev,pic} to
libstdc++6-{dbg,dev,pic}, with Conflicts and Replaces.
Proposed solution 2:
1) In gcc-4.1, change libstdc++6-4.1-{dbg,dev,pic} to Conflict with
and Replace libstdc++6-{dbg,dev,pic}.
Proposed solution 3:
1) Do not build libstdc++6-{dbg,dev,pic} from gcc-3.4 anymore.
2) In gcc-defaults, build libstdc++6-{dbg,dev,pic} that, in etch,
depend on libstdc++6-4.1-{dbg,dev,pic}.
I personally vote against solution 2, since we don't build g++-3.4
anymore and so the libstdc++6-{dbg,dev,pic} from gcc-3.4 are useless
anyway. I think solution 3 is the best if we want to support multiple
versions of g++.
