[perl #60312] [BUG] OpenBSD Smolder test failures

Here's an update based on a recent Smolder report
(http://smolder.plusthree.com/app/public_projects/report_details/21469);

veracity.t:  passing

arithmetics.t:
ok 7 - negate -0.0 # TODO -0.0 not implemented, TT #313 : still not passing
(Why is this showing up yellow rather than green on the Smolder report
if it is 'ok'?)

complex.t:
not ok 380 # TODO sinh of -2-3i
not ok 381 # TODO sinh of -2-3i

float.t:
not ok 23 - neg 0 # TODO -0.0 not implemented, TT #313

#   Failed (TODO) test 'neg 0'
#   at t/pmc/float.t line 512.
#                   '0'
#     doesn't match '/^-0/
# '

So I would say that only one of the six tests I originally flagged has
been clearly resolved.
