Some packages event depend on libstdc++-v3 even if gcc-3.3 is installed.
I suggested virtuals for each libstdc++-version a long time ago since
they are provided by either gcc or seperate libstdc++ ebuilds. It was
rejected by i think vapier or azarah.

Furthermore, i suggested that portage may analyse installed binaries for
dependency on a specific libstc++ version and it may record an
additional depency for such packages.
This would solve the "emerge depclean uninstalls in-use libstdc++
library" easily. Of course, this might need heavy changes to portage.
