branch creation

Hi,

But if you want to use it for any kind of ABI modifications I see an already existing branch with a rather good name: libstdcxx_so_7-branch. It is documented as not maintained anymore, could we recycle it for this purpose ?

Sure we can, the only problem I can see is that few things in it, breaking the ABI for good, may be worth preserving in its new incarnation. The branch-specific ChangeLog should help about that. And probably you will also find something in <algorithm> which we do not want to pursue, at the moment at least, that is the collapse of the algorithms coming in pairs, taking and not taking a predicate, because it's too tricky wrt proxy iterators. Are you willing to disentangle those issues? As far as <algorithm> is concerned, probably you can just replace everything with the mainline version, as a start.

I don't know, maybe it's easier to just create a so_7-2, document that the old one is frozen, and in a more relaxed way forward port the interesting bits of the old branch to the new one.
