+You will see regression failures for the float4 and float8 regression
+tests on the NaN and inf I/O functions. This is due to a bug in SCO's
strtod
+library function on BOTH UnixWare and OpenServer. It's slated to be fixed

+You might also see Join test failures due to ordering differences, and
these
