Error with PostgreSQL 8.0 beta 2, in "make check" on Mac OS X (10.3.5)

I downloaded beta 2, unpacked it into its own directory, became (via
sudo) the "postgres" user, and did the whole "configure" and "make"
business.

When I ran "make check", all of the tests passed successfully, except
for the "geometry" test, which failed.  Looking at regression.diffs
(enclosed as an attachment), it looks like the fourth test was expected
to have a (-0, 0) for a result, but actually had a (0,0) as a result.
Obviously, -0 and 0 are mathematically equivalent, but "make check"
doesn't seem to think so!
