I'm afraid there is no good solution for this.  I mean, afaik, there is no IDE 
which is able to perform "intelligent" substitutions in C++, as it would 
require being able to perform full analysis of the code, detect collisions, 
etc.  It exists for simpler languages (from the syntactic point of view) such 
as Java, but for C++, you might have to simply perform substitution with, say 
perl, something like

        perl -pi.bak -e 's{\bMyFormerClassName\b}{MyNewClassName}g' *.{cc,hh}

I heard about a powerful environment for C++ under Emacs, but I forgot its name.

[looking for it...]

It might be http://cedet.sourceforge.net/semantic.shtml.

That page reports that "David Ponce has ported Bison to Emacs Lisp".  I don't 
know what that means, but I'm curious :)
