Patch for the first case: enum.c, EnumDeclaration::semantic, line 109

        assert(e->dyncast() == DYNCAST_EXPRESSION);
        e = e->semantic(sce);
-        e = e->optimize(WANTvalue);
+        e = e->optimize(WANTvalue | WANTinterpret);
        // Need to copy it because we're going to change the type
        e = e->copy();
        e = e->implicitCastTo(sc, memtype);
-        e = e->optimize(WANTvalue);
+        e = e->optimize(WANTvalue | WANTinterpret);
        number = e->toInteger();
        e->type = t;
