Using emacs macros and stuff, I can create a proxy class which has the same signature, but each method calls a C macro which calls the original class method, and does other stuff.

A class or a namespace?

For ad hoc code generation, I usually end up with awk and sed. I just did this wrapping 
thing with a java class definition ( no actual source code) and could pretty much use lynx to render the javadoc html, extract
method signatures, and use awk to generate methods with sed and finally
vi to touch stuff up.  The generated class contained an instance of the original class that
was simply called in each generated method after my custion code,if any, executed. 
I wasn't just interested in wrapping as I also made a fake version for
unsupported operations. 

I'm not really sure you need a c++ library for this but I imagine there are cases
where it would be worth the learning curve. Personally, I try to learn generic
tools with wider applicability unless I need something more specialized.
