The "zsystem supports" command was added to this module for this
purpose.  "zsystem supports anyoldrubbish" simply returns status 1
unless the zsystem module has been provided with an internal feature
called anyoldrubbish.  It's not visible at the zmodule interface,
however; you have to load the module and run the command.

Explicitly linking against GNU libraries might have legal consequences.
We print a warning when we do this with libgdbm as it means the binary
is covered by the GNU public license (as they call it).  It depends on
the licence (as I call it) for the library whether this would apply
here.

P.S. Tests reveal zsystem does not currently support anyoldrubbish.
