[Bug ada/29462] New: Sign ignored on fixed point multiplication

["dewi dot daniels at silver-software dot com" <gcc-bugzilla at gcc dot gnu dot org>]

The sign seems to be ignored when multiplying a named number with a fixed point
value.  Converting the named number to a fixed point type seems to work around
the problem.  See the example below:

with Ada.Text_IO;
procedure Test
is
   type T is delta 0.1 range -1.0 .. 1.0;
   X : constant := -1.0;
   Y : T;
   package T_IO is new Ada.Text_IO.Fixed_IO (T);
begin
   Ada.Text_IO.Put ("X = "); T_IO.Put (X); Ada.Text_IO.New_Line;
   Y := -1.0;
   Ada.Text_IO.Put ("Y = "); T_IO.Put (Y); Ada.Text_IO.New_Line;
   Ada.Text_IO.Put ("X * Y = "); T_IO.Put (X * Y); Ada.Text_IO.New_Line;
   Ada.Text_IO.Put ("T (X) * Y = "); T_IO.Put (T (X) * Y);
Ada.Text_IO.New_Line;
end Test;
