    ada: Fix spurious emissions of -gnatwj warning
    
    Before this patch, the compiler would erroneously emit a warning
    about the use of parentheses for array aggregates being discouraged
    in some situations. Those situations were the ones where array
    aggregates were used as generic actuals when instantiating generic
    packages defined in the runtime library.
    
    This patch fixes this issue by looking at the Ada version explicitly
    specified by the user instead of the Ada_Version flag which is
    always set to the latest Ada version when compiling code from the
    runtime library.

            * sem_aggr.adb (Resolve_Array_Aggregate): Tweak conditions for
            warning about use of parentheses for array aggregates.
