Global qualification in a class declarations class-head
- by gf
We found something similar to the following (don't ask ...):
namespace N {
struct A { struct B; };
}
struct A { struct B; };
using namespace N;
struct ::A::B {}; // <- point of interest
Interestingly, this compiles fine with VS2005, icc 11.1 and Comeau (online), but fails with GCC:
global qualification of class name is invalid before '{' token
From C++03, Annex A, it seems to me like GCC is right:
the class-head can consist of nested-name-specifier and identifier
nested-name-specifier can't begin with a global qualification (::)
obviously, neither can identifier
... or am i overlooking something?
