Looks like it, yes.  As I've explained, we can't do it on src/gdb/
alone, because the CXX make variable is passed down from the top level,
which would override whatever we set in gdb/'s configure/Makefile.

I want to give it a try, though.  It just requires time and getting
the patch into gcc and merged back.  I don't think that should hold
back the proposed series (or pieces of it).

I wasn't originally meaning to unconditionally add -std=c++11 though,
but instead to only add it if the compiler supports it, in order
to conservatively still support C++03-only compilers.

But if we agree to go full-on C++11, then I'll be more than
happy to make gdb's configure error out on non-C++11 compilers.

Thanks,
