(Feel free to correct me if this use of 'variadic' is not the correct terminology.) Please note that I'm not after working on ranges of arguments. I'm rather looking for a max function which is applicable in all the examples below:

Compilation with the gcc variadic template compiler and run of
attached produces output:

/home/evansl/download/gcc/4.5.1-release/install/bin/g++ -Wl,-rpath

So, replacing add with another binary op, such as max, should work.
