I found one
http://gcc.gnu.org/ml/gcc/2005-01/msg01760.html

and a link from there to,
http://www.open-std.org/JTC1/SC22/WG21/docs/cwg_closed.html#209

I don't understand the reasons for using access control in the friend
statements except that it probably makes access control easier to write
and apply in the compiler (ie. less exceptions)
