The following invalid code snippet causes a very redundant error message
since gcc 3.4.0:
===================
typedef int X;
typedef void X;
===================
bug.cc:2: error: conflicting declaration 'typedef void X'
bug.cc:1: error: 'X' has a previous declaration as `typedef int X'
bug.cc:2: error: declaration of `typedef void X'
bug.cc:1: error: conflicts with previous declaration `typedef int X'
bug.cc:2: error: declaration of `typedef void X'
bug.cc:1: error: conflicts with previous declaration `typedef int X'
With previous compilers I just get two line:
bug.cc:2: error: conflicting types for `typedef void X'
bug.cc:1: error: previous declaration as `typedef int X'
The C frontend is not affected.
