           Summary: Wrong scoping for function parameter names?
           Product: clang
           Version: trunk
          Platform: PC
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P
         Component: C++
        AssignedTo: unassignedclangbugs at nondot.org

Clang rejects this code in C++ mode:

  typedef int a;
  void f(int a, a b);

while EDG and GCC accept it (the name 'a' binds to the typedef in global
scope).

Note that this code is ill-formed in C, indicating that the scope of function
parameter names differs between the two languages. I haven't been able to track
down the wording that makes this different.
