Also consider:

void g(c)
 enum m{q, r} c;
 {
 }

What is the scope of m, q, and r?

Subclause 6.1.2.1 says on page 20, lines 28-29 “... appears outside of any block or list of parameters, the identifier has file scope, ...”

It says on page 20, lines 30-31 “... appears inside a block or within the list of parameter declarations in a function definition, the identifier has block scope, ...”

Now the above three identifiers appear outside of any block or list of parameters but they are within the list of parameter declarations.

Who wins?

Comment from WG14 on 1997-09-23:

Response

The scope of m, q, and r ends at the close-brace (block scope). The operative wording is the more specific statement on page 20, lines 30-31 “... appears inside a block or within the list of parameter declarations in a function definition, the identifier has block scope, ...”

As an example, in the code fragment:

void g(c)
 enum m{q, r} c;
 {
 }

the scope of m, q, and r ends at the closing brace of the function definition (block scope).
