Then maybe you've modified some compiler code common for languages and
cause GCC to misbehave on libstdc++ code (then stage 1 libstdc++ fails),
or maybe it causes GCC to miscompile itself and generate a compiler
misbehaving on libstdc++ code (so stage 2 libstdc++ fails). Or maybe
some modification to the building system causes libstdc++ built with
wrong CXXFLAGS. Who knows? We have no idea how the code is modified.
