The Ada compiler was incorrectly fetching the root type when handling the Image attribute for derived enumeration types, bypassing representation clauses defined on the derived type itself. This commit ensures that the compiler respects representation clauses on derived enumeration types when generating the Image attribute, by sticking to base types. A new test case, gnat.dg/enum6.adb, validates the fix.
