[Bug c++/24090] New: gcc 4.1.0 20050926 - friends not visible outside class

[jaffe at broad dot mit dot edu]

If test.cc is:

class F { 
   friend void global_f() {}
};
class G {
   void member_of_g() { global_f(); }
};

then gcc -c test.cc yields

test.cc: In member function 'void G::member_of_g()':
test.cc:5: error: 'global_f' was not declared in this scope

which appears to be wrong.

A friend declaration only changes the visibility, it does not declare the 
name.

See PR 7874 (http://gcc.gnu.org/PR7874) for more discussion.  Basically gcc now
conforms to the ISO C++ standard in this regard.  This is a change from earlier
releases, and is documented at http://gcc.gnu.org/gcc-4.1/changes.html.  The old
behaviour was declared to be deprecated in http://gcc.gnu.org/gcc-3.4/changes.html.
