Andy,

Nice one. I never thought of that situation. I'll pinch it if I may.

All three macros are trivial, but they are my first(s).

I've been having a look at some of the available C compilers and
am experimenting to see if some well crafted macros can provide
things that some of the c compilers can't - like signed integer
math for one.
