Juno Krahn <juno.krahn at nih dot gov> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |juno.krahn at nih dot gov --- Comment #7 from Juno Krahn <juno.krahn at nih dot gov> 2012-11-26 19:51:55 UTC --- IMHO, this is valid code regardless of whether the binary argument types can be seen as equivalent. The standard is quite vague, but see my comment at bug 48858 comment 13. The standard defines that the binding label itself is a unique global entity, but does not specify that the interface definition is unique.
