The guidelines actually confused me a little.  The first bullet for 
calling min or max has:

If you want to call std::min() or std::max():

     * If you do not require argument-dependent look-up, use 
(std::min)(a,b).

I got caught up in the ADL part and didn't realise that the parenthesis 
were there to stop macro expansion not to stop ADL.
