If the delta_aggregate feature is used, the -gnat2020 or -gnatX switch
must be given.
The following test must get an error if neither
-gnat2020 nor -gnatX is specified:
gcc -c delta_aggregate.ads -gnat2012
delta_aggregate.ads:4:18: delta_aggregate is an Ada 202x feature
delta_aggregate.ads:4:18: compile with -gnatX
package Delta_Aggregate is
X : String := "Hello";
Y : String := (X with delta 1 => 'h');
end Delta_Aggregate;

* par-ch4.adb: Minor wording change in error messages.
* sem_aggr.adb (Resolve_Delta_Aggregate): Emit an error for Ada
versions prior to Ada 2020.
