[Bug c++/28142] New: Template friend declaration and dependent names

["wolfgang dot roehrl at gi-de dot com" <gcc-bugzilla at gcc dot gnu dot org>]

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<some include paths>
      -D<some #define's>
      X.CPP -oX.O


// file X.CPP

template <typename T_>
struct S
{
    struct B;
};

class C
{
    template <typename T_>
    friend struct S<T_>::B;     // <--- line 10
};


The compiler gives the following error message:

X.CPP:10: warning: `S<T_>::B' is implicitly a typename
X.CPP:10: warning: implicit typename is deprecated, please see the 
   documentation for details
X.CPP:10: error: typename type `S<T_>::B' declared `friend'

According to 14.5.3/6 the compiler should accept the code above.


Kind regards
W. Roehrl
