Joe, there is no doubt that those programs compiled before 4.0 and, by
and large, worked before. The latter point it's a delicate matter of
details, I don't have a complete answer right now, sorry, because, as
repeated once more by Andrew (I thought it was enough ;) the behavior of
the compiler pre-4.0 was wrong in some corner cases, the wrong function
was friended. Then 4.0 changed that in a non-compile and 4.1 finally is
completely ok.
