|  As I mentioned earlier, I don't have access to a current Visual C++  
|  compiler, but I'm happy to add relevant warning suppressing  
|  #pragmas...sounds like it doesn't like me naming arguments in  
|  template declarations...

Yes, somehwat annoyingly, but easily cured by commenting it out /* source */
(or deleting, but then the helpful documentation is lost, so not my
preference).  A Minor isse but a minor thing to cure.

|  I think it's the opposite problem - the cxxabi.h header has a bunch  
|  of references to size_t that aren't qualified with std::. Anyway, I  
|  think the problem went away (again, per Deane) when I moved 
|  my using  
|  namespace boost::mpl; inside the boost::units namespace. Again,  
|  please correct me if I'm wrong...

John Maddock has used

using namespace std;

WITHIN the function scope

to overcome what I think was the same widespread problem in math
distributions with not finding pow in namespace std.

However, I am on holiday for 10 days, so I can't test for you now.
