Hi!
I was just using gcc3.0 (CVS head) for POOMA and now noticed that
even at -O the NearestNeighbors test from the Field testsuite is
failing (works at -O0). Also gcc3.0 contains loop optimizer bugs
that cause lots of regressions if -funroll-loops is used. So I
recommend people _not_ to use gcc3.0 to do anything with POOMA.
I'll check whats up with gcc3.2, but that seems to be confused by
either my binutils or my libc version.
Richard.
