Redeclaration Question

[Curt Wohlgemuth]

I have a question on a possible constraint violation in an object
redeclaration.

Section 3.5 of the 7 Dec dpANS says, "If an identifier has no linkage,
there shall be no more than one declaration of the identifier (in a 
declarator or a type specifier) with the same scope and in the same name
space, except for tags..."

Is this then a constraint violation?  Seems to me that it is...

main()
{
   extern int i;
   int i;
}
