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 ?

I guess here we have a compile-time checking problem; we would need
some more or less gross configure hack to try to detect which ABI is
deployed; suggestions appreciated.
Many thanks for the (otherwise) excellent gcc :-)
ATB,
