Actually, I suspect the problem is that isinf() on your platform
returns 1 for any infinity (rather than -1 for negative infinity and 1
for positive infinity). Some existing code in float4out() and
float8out() assumed that a positive return from isinf() indicated a
positive infinity, which is not per C99.

Anyway, Tom and I worked through this issue, and a couple other
portability problems with the recent float changes, via private
email. The current patch is attached -- Tom hasn't yet gotten back to
me on whether this fixes the problem for him on HPUX, but it fixes my
OS X box.
