Well, the early returns on that are promising, but we have another
problem: prairiedog, jacana, and probably other old BF members are
failing the new regression test cases. It appears that what the test
script assumes will produce a NaN or Inf float doesn't work in 5.8.x
perl:
$ perl -e "print 0 + 'NaN'"
0
$ perl -e "print 0 + 'Inf'"
0
I googled a bit and found these recommendations on stackoverflow:
my $inf = 9**9**9;
my $neginf = -9**9**9;
my $nan = -sin(9**9**9);
These do seem to produce the desired results, at least on the
couple of Perl versions I checked, including 5.8.3.
