(main): Move declarations of SIZE and TOTAL to where they won't cause "unused" warnings when NO_MEM is defined.

(main):  Move declarations of SIZE and TOTAL to where they won't cause
"unused" warnings when NO_MEM is defined.
(promotions):  Explicitly declare return type (to avoid warnings).
Always return a value.
