Linux 2.4.10-4GB i686 (SuSE 7.3)
>Description:
g++ 3.1 rejects access to a private class member by the
default argument of a friend function.

But clause 11, paragraph 7, of the C++ standard seems to
allow the access.

g++ -v gives the following:
  Reading specs from /home/lidiaadm/gcc-3.1/gcc-3.1/lib/gcc-lib/i686-pc-linux-gnu/3.1/specs
  Configured with: ./configure --prefix=/home/lidiaadm/gcc-3.1/gcc-3.1 --enable-threads=posix --enable-languages=c,c++
  Thread model: posix
  gcc version 3.1

gcc 3.0.3 and 2.95.3 (Linux/i) as well as 2.95.2 
(Solaris 8 / UltraSparc) show the same behaviour.
