v6.4 regression test failures

Hello,
I just compiled v6.4 on my Sparc2 running Solaris 2.6 using GCC v2.8.1.
Running the regression tests produced the expected failures in "float8"
and "geometry" and also produced failures in "abstime", "tinterval", and
"horology".

I can send you the output of these specific parts of the regression
tests if it would be of benefit to you.

Thanks,
Lance
