Regression on 7.1.2 fails 17/76 - is it up to date?

This *is* supposed to be the forum for naive questions, so here goes: Are the regression tests still valid?

I'm asking, because my installation reports: "17 of 76 tests failed, 1 of these failures ignored."  This seems an awful
lotfor a recent download.....  It is a known problem, or do I need to investigate further? 

There is a bug report relating to PostgreSQL 7.0.3 which seems similar
(http://www.ca.postgresql.org/bugs/bugs.php?4~236),but surely this is fixed by now.....?  And if not: any thoughts on
whetherit is the database or the regression test that is the problem?
