Perhaps you could do some investigation into where the bottlenecks are.
Using the -c, -E, and -S switches to control how much work the compiler
does, you can work out, relative to gcc, where g++ is spending all of its
time.

Of course, this might be hard, because you might need some complex C++ to
cause g++ to slow down, but you can't use the same test input for gcc,
being a C compiler.
