I already know a couple ways around the bug, starting from going back
to

  if Dir (Dir'Last) =3D '\' then
     return Dir;
  else
     return Dir & '\';
  end if;

all the way to

  function Validate (Dir : in String) return String is
    Validated : constant String :=3D (if Dir (Dir'Last) =3D '\' then Dir
else Dir & '\');
  begin
    return Validated;
  end Validate;

This has nothing to do with syntax, which is correct AFAICS (please
note the above example with the Validated constant string compiles
just fine). It's a plain simple bug.

I often do.
