Code extract:

      Signs : constant array (1 .. 2, 1 .. 2) of Sign :=
        [[Sign (Left.Lower_Bound), Sign (Left.Upper_Bound)],
         [Sign (Right.Lower_Bound), Sign (Right.Upper_Bound)]];

The error message is ieee1788.adb:347:10: (style) space required [-gnatyt], which is about the middle line.

For gnatformat it is fine.

I tried to add a space, between the brackets and after the second bracket, but always get the same error/ one that there are too many spaces then.
