Re comment 12 - as someone who regularly needs to understand gcc diagnostics, I
disagree completely.
Understanding a failure to look something up, the single most important thing
to know is the key being looked up, and in this case the key is the
function/operator name and the argument types.
gcc used to output that information, and removing that was a regression,
completely independently of whether the current diagnostics make any sense.
Given that no significant progress has been made with fixing the current
diagnostics in nearly a decade, it is puzzling to me why the obvious & simple
fix of reverting to the previous, useful, diagnostics, has not been made.
