Currently, --enable-languages=c --enable-build-with-cxx fails because
neither the C++ compiler nor libstdc++-v3 are built in Stage 1, but in
Stage 2, CXX is set to .../prev-gcc/g++ and other variables are set
accordingly. Is this combination supposed to work?
If yes, is it supposed to only build the C++ compiler and associated
library in Stage 1 but not in later stages?
If no (to the first question), then shouldn't configure fail early?
(This is related to PR bootstrap/40950, but only in that it causes a
similarly-looking failure, AFAICS.)
Thanks,
Ralf

It would be nice if it worked. It's kind of an odd thing to do, though,
so it's OK if it fails.

It can only work if it builds the C++ compiler in every stage except the
final one.

Yes, I think it should either work or fail early.
