Building dejagnu with latest GCC

[kenner at vlsi1 dot ultra dot nyu dot edu (Richard Kenner)]

I'm trying to recreate my tool environment, but I get the follow.
I don't know C++, so don't know if this represents a GCC or Dejagnu
problem.  Any help would be appreciated.

(I'm still looking for a pointer to the versions of tools that GCC
maintainers should be using, by the way.)
