I said that this is much better than an explicit cast.  It is.  And it behaves
identically.

If the user expects C to provide tests for "mathematically different", the
user has some learning to do.

If, as I said, the user uses explicit casts, that's not good.  Much better
already is to use implicit casts, as I said; and much better than that is
to fix the problems at the root (use proper types everywhere), as I said.

There is no simple fix, so GCC cannot give good guidance.

Oh, and don't try to insult me please, I'm much too dumb for that.
