We have a SONAME bump happening due to the Vigra 1.10.0 transition [1] which generally could let spare a "v5" package when the two transitions would be combined, isn't it?
However, I think it's better to adopt what has been already changed for 1.10.0+dfsg-9ubuntu1 to update Vigra for 15.10 (renaming libvigraimpex5 to libvigraimpexv5 and rebuild) - there's really no need to avoid this. We have some other serious issues open for Vigra (with the Lenna image set [2] and test suite problems in Mips), so I suggest we do it that way: I'm going to prepare a "v5" 1.9.0+dfsg-11 for unstable in the next days and check the reverse deps. After that we go for a "v5" 1.10.0+dfsg-10 in experimental and check the reverse deps on that, that would close the stdc++6 transition as the next thing to do on Vigra.
