Isn't it also an error to build libitm unless: (1) --enable-languages=c++ is asserted, or (2) --enable-libitm is asserted? For (2) arguably it should imply that c++ will be built, or disallowed. We're seeing two failure modes noted in comment #1 and comment #2 for systems with not-so-modern versions of g++ installed.
