    [Ada] Refine type for checking number of pragma arguments
    
    Code cleanup.
    
    gcc/ada/
    
            * par-prag.adb (Check_Arg_Count): Change parameter type from Int
            to Nat, because this parameter is compared to Arg_Count variable
            which is of type Nat. Also, it wouldn't make sense to check for
            negative number of pragma arguments.
