           Summary: rejects-valid: Conflicts Between typedefs/enums and
                    Namespace Member Declarations
           Product: gcc
           Version: 3.2.2
            Status: UNCONFIRMED
          Severity: minor
          Priority: P2
         Component: c++

G++ rejects the following valid code, claiming that 'void A::Thingo()' is a
redeclaration of 'typedef int Thingo'.
 
The error goes away if:
  - you wrap the typedef in an anonymous namespace;
  - you include the definition of void A::Thingo() in
    namespace A.
                                                                               
                         
The error remains if:
  - you replace the typedef with enum { Thingo };


---- test.cc ----

typedef int Thingo;
  
namespace A
{
    void
    Thingo();
}
  
void
A::Thingo()
{
        ;
}
  
int
main()
{
    A::Thingo();
    return 0;
}

---- EOF ----
 
$ g++ test.cc
test.cc: In function `void A::Thingo()':
test.cc:11: `void A::Thingo()' redeclared as different kind of symbol
test.cc:1: previous declaration of `typedef int Thingo'
