This commit modifies the Ada compiler to align with the Language Reference Manual’s rules regarding accessibility levels. Specifically, it disables some static accessibility checks when dealing with dynamic contexts, such as access discriminants and actual parameters, by passing Zero_On_Dynamic_Level to the accessibility calculation functions. This ensures the compiler accurately determines accessibility in situations where it varies at runtime.
