dbms_defer package invalid in Oracle 8.1.7

I downloaded Oracle 8.1.7 for Solaris from http://technet.oracle.com. Installed it, migrated a test database.

dbms_defer was invalid after the upgrade.

Ran dbmsdefr.sql, which contains the dbms_defer package.

The package definition contains procedures, like time_arg, which have definitions in the package header, but not in the package body.

Here are the results from show errors after trying to recompile the package body:
