I get the same error on 3.3.1 (20030707), 3.2.3, 3.0.4, and 2.95.3. Both with the mainline,
I get:
pr11876.cc: In instantiation of `A<int>':
pr11876.cc:17: instantiated from here
pr11876.cc:4: error: class `A<int>' is implicitly friends with itself
pr11876.cc: In instantiation of `A<float>':
pr11876.cc:24: instantiated from here
pr11876.cc:4: error: class `A<float>' is implicitly friends with itself
And with 2.91.66 I get the same as the mainline expect they are warnings instead of
errors, I do not know what is the right thing though.
