While PR53646 claims that c++98 and c++11 should be ABI

This is pretty nasty for LibreOffice (and no doubt others). We can, and
often do depend on rather a number of system C++ libraries and at a very
minimum, having no simple way to detect which C++ ABI we have to build
against 'old' vs. 'new' - is profoundly unpleasant.
Is there no chance of having a bug fix that is a revision of the
(unintended?) ABI breakage in this compiler series ?
That's the direction I'd prefer to see (reversion until we're ready to
make the wholesale ABI changes). Not sure what the libstdc++
maintainers are thinking right now.
