Do we want to prevent the user doing this? Or is the idea to prevent
them doing it accidentally. Why not add a call like

sharedprivate (fullfile (octave_config_info ("localapioctfiledir"),
"polynomial"))

to

usr/share/octave/3.0.0/m/polynomial/PKG_ADD

and

sharedprivate (fullfile (octave_config_info ("localapifcnfiledir"),
"polynomial"))

to

usr/lib/octave/3.0.0/oct/x86_64-pc-linux-gnu/polynomial/PKG_ADD

and have the "sharedprivate" function register with the symbol table
code that an additional legal path to the private directories.. This
gives us the freedom to add dependent private directories anywhere and
prevents the user accidentally obtaining access to the private functions..

David
