I can't find the answer to this in the LRM. I'd like to rename the negation
operator (unary -) in order to avoid a 'use' clause. I can manage to rename
the subtraction operator but I don't know how to do it with the negation
operator. Can someone tell me how it can be done, if it can be done?
TIA

same as all the other renames, the difference with the subtract operator is
there is only 1 parameter e.g.
procedure main is
package nested is
type an_integer is range -10 .. 10;
end nested;
function "-" (x : in nested.an_integer) return nested.an_integer
renames nested."-";
a, b : nested.an_integer;
begin
a := 10;
b := -a;
end main;

Much better approach in Ada 95, use a USE TYPE clause.
Even those allergic to use clauses find this acceptable :-)
