The problem is that there is nothing special about the main-program procedure.
Specifically, it could be withed and called from something else, or call itself
recursively. In either case, its declarative region, with its declaration of the
function, would be nested deeper than the declaration of the access type. Since
this is a compile-time check, it rejects anything that might be deeper, even
when it never is.
The basic rule with named access-to-subprogram types is that the actual
subprogram must be declared in a library-level package.
