--- Comment #11 from Jonathan Wakely <redi at gcc dot gnu.org> ---
OK, so we can just drop the alias symbols. But that means that libstdc++.so=
 on
Solaris 11.3 and 11.4 will be incompatible. Is that acceptable?

If not, maybe the right thing to do is just add the symbols to GLIBCXX_3.4.=
29
for Solaris 11.3 as well, for consistency with the library on 11.4

That would mean that libstdc++.so.6.0.30 has symbols in the GLIBCXX_3.4.29
version that weren't in libstdc++.6.0.29=
