[Bug c++/20420] New: Unrecognized double declarations

[wolfgang dot roehrl at de dot gi-de dot com]

Dear all,

I would like to post a bug report for the GNU C/C++ compiler 3.3-e500.

We use the compiler to generate code for a PowerPC processor.

Used invokation line for the GNU C++ compiler:

ccppc -c -x c++ -ansi -Wall -Werror -mcpu=8540 -fverbose-asm -mbig
      -fmerge-templates -mmultiple -mno-string -mstrict-align -O3
      -fno-exceptions -fno-rtti -fno-builtin-printf
      -I<different include paths>
      -D<differen #define's>
      K.CPP -oK.O


// file K.CPP

class B
{
protected:
    enum E { E1, E2, E3 };
    struct S { int i; E e; };
};

class D : private B
{
public:
    using B::E;
    using B::S;

private:
    enum E {};
    struct S {};
};


The compiler does not complain about the double declarations of enum E and
struct S. (By the way, the Comeau online compiler recognizes the doubly
declared items.)

Kind regards
W. Roehrl
