When describing K&R1 function definitions, the Standard says in section 6.7.1
that "If the declarator includes an identifier list, ...  An identifier
declared as a typedef name shall not be redeclared as a parameter." Since this
is not stated in the context of "ANSI" function definitions (those with a
parameter type list), given
   typedef int x;
does this mean that
   foo1(int x) { }
is conforming but that
   foo2(x) int x; { }
is not conforming? Also, what about
   foo3(x) { }
Even though the declaration of x is not explicit (there is, for example, no
"int x;", is this a redeclaration of x as a parameter, in which case this is
also not conforming?
