That does not make them "right", nor does it turn your invalid code
into valid code.
| struct tag{};
|
| struct A {
| tag t; // *
| typedef int tag;
| };
|
| *omit this declaration and everything is fine for g++
|
| error msg on g++3.4.4:
|
| error: declaration of `typedef int A::tag'
| error: changes meaning of `tag' from `struct tag'
|
| Why would the outer tag declaration conflict with the tag declaration in
scope
| A? This is not an error that I would have expected intuitively which is why
I'd
| like to bring this up again.
The C++ standard says that your program is ill-formed.
