No matter whether C++ will happen or not -Wc++-compat is already useful
(for the 64-bit offsets upstreaming). This is why I ask for it on its own.
While -Wc++-compat enables fixing the 64-bit offsets in GDB it is only like
1% (random guess) of GDB bugs fixes C++ enables us to do. So the decision of
-Wc++-compat is orthogonal to the C++ decision.

There is hopefully not much help needed, Matt Rice was offering to update
archer-ratmice-compile-Wc++-compat, and I think one can safely verify the
patch is valid (besides some eyes review) also by comparing byte-by-byte the
compiled stripped binaries.
Thanks,
