GNAT is right to flag that, it is clearly illegal, since sub_main on the
right would refer to sub_main on the left if it was allowed to (which
it is not), and not to the outside sub_main. In fact the rule is that
sub_main is introduced by the declaration, but cannot be refrerenced
until the declaration is complete.

To rewrite this correctly, use appropriate qualiffication for the
sub_main reference on the right hand side to get the one you want!
