Description Ivan Godard 2005-07-31 05:37:01 UTC 
typedef int A;
struct foo{
A A;
};

compiles in 3.4.0 and on Comeau, but on 3.4.2 you get:


changedMeaning.cc:3: error: declaration of `A foo::A'
changedMeaning.cc:1: error: changes meaning of `A' from `typedef int A'

So who's right, you or EDG?

GCC is.  See PR 17353 and [basic.scope.class] of the standard.

The code is ill-formed; no diagnostic required.  GCC-3.x, x < 4 used to
issue a diagnostic as a QoI.  A regression was introduced in 3.4.0,
and fixed later.

Both, but we're better ;-)
