[Bug c/13728] New: Duplicate parameter names not detected

[jsm28 at gcc dot gnu dot org]

void f (int fred, int fred);
void f2 (int fred, int fred) {}

does not get any diagnostics with current 3.4 or 3.5 CVS.  3.3.2 gives
proper errors (albeit with some duplication):

t.c:1: error: redefinition of `fred'
t.c:1: error: `fred' previously declared here
t.c:2: error: redefinition of `fred'
t.c:2: error: `fred' previously declared here
t.c: In function `f2':
t.c:2: error: redeclaration of `fred'
t.c:2: error: `fred' previously declared here
