I don't think the UNIX behaviour is identical across all Unices. The reason why
MacPerl gives a full path is that it has no reasonable notion of a "current
directory" on which to base relative paths as long as no script is running
(Once a script is started, the relative path is based on the location of the script).

Numeric vs. string context. Try

print $]+0;

The distinction was dropped in Perl 5 (Note that the above indicates
perl4.036), presumably because RCS ids are not overly helpful for users.
