Yes, I remember this one. But that must not be the option I believe I've=

seen somewhere, as `simplifiable_expressions` is about the opposite here=
:  =

it would flag an universal expression to which is applied an explicit ty=

conversion when it do not serves an ambiguity resolution.

Honestly, I now believe the error was rather mine, as I could not  =

reproduce the case, and checked even with 32 bits GNAT, `root_integer` i=
s  =

64 bits width, according to the System package. Or else, may be this was=
  =

the effect of an operator which was visible/invisible due to some `use  =

type` added or missing (I've changed so much things since).
