It means exactly what it says. You're trying to take the access
value of a subprogram that is nested more deeply than is the
place where the access type is declared.
To remedy this, you need to do one of two things, viz.:
1. Declare the subprogram at library level -- i.e., not in
a package or nested within another subprogram
2. Use 'Unrestricted_Access instead of 'Access, if you're
using GNAT, and if your are certain that the lifetime of
the subprogram is at least as long as the lifetime of the
access type.
