[Bug c/14133] New: Duplicate diagnostics on redeclaration

["jsm28 at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

void f();
        void f(int, ...);

yields duplicate diagnostics:

t-dupdiag.c:2: error: conflicting types for 'f'
t-dupdiag.c:2: note: a parameter list with an ellipsis can't match an empty
parameter name list declaration
t-dupdiag.c:1: error: previous declaration of 'f' was here
t-dupdiag.c:2: error: conflicting types for 'f'
t-dupdiag.c:2: note: a parameter list with an ellipsis can't match an empty
parameter name list declaration
t-dupdiag.c:1: error: previous declaration of 'f' was here

Caused by one of Zack's patches.  Previously mentioned in mail but
now filing a bug to track it as a regression.
