3.7.1, footnote 81:  "A parameter is in effect declared at the head of the
compound statement that constitutes the function body, and therefore may
not be redeclared in the function body (except in an enclosed block)."
This isn't exactly obvious from 3.7.1, but a careful reading of the scope
rules in 3.1.2.1 confirms it:  a function definition sets up *one* scope,
not two, for variables.
