The fix is in CVS.  I've been pestering Marc to wrap up a snapshot
tarball of REL7_3_STABLE branch tip, but he hasn't got round to it.
So probably the easiest answer for you is to check out the branch
from our anonymous-CVS server --- see basic instructions at
http://www.ca.postgresql.org/users-lounge/docs/7.3/postgres/cvs.html
but note the initial checkout command should be
    cvs ... co -P -r REL7_3_STABLE pgsql
to get the stable branch rather than development tip.  Note you will
need a fairly current version of bison to build from source.
