Thanks... indeed I was mistaken that isinff() is part of C99.  I could
have used isinf() for floats also as it there seem to be sizeof checks
within that macro to insure that no implicit promotion takes place.

I've currently fellback to fpclassify since I thought that would be more
portable, but it infact it's as portable as the isinf/isnan macros (ie.
C99).  What /might/ have helped on Solaris (or at least newer Solaris
versions) is the "#define _ISO99_SOURCE".

But the current code should also work for FreeBSD.

Cheers,
