This patch, when applied in src/pl will unbreak plperl in

7.0.2 release. Sorry, if that's fixed ages ago - I don't track
development versions of PostgreSQL.

Patch is just a little bit tested (some valid functions created and
successfully run as well as some erroneous ones created and emitted proper
error messages when used).

My platform is FreeBSD 5.0-CURRENT (with perl 5.6.0 provided in the
base system).
