If adding scope attributes every time more than one variable is declared
adds to the already immense bulk of C++ debugging information, I'd
prefer to live with the bug myself.
Out of interest, why? I haven't looked into this properly yet, so I
don't know what problems it might cause. Will having this much more
debug info significantly slow down GCC/GDB? Will it have other
problems?
