With the message from Bob Soliday I think we are now OK for vxWorks, solaris, Linux (at least recent releases), and WIN32.

What about HPUX and VMS?

HP-UX provides both isnan() and isinf(), either as macros defined in math.h
or as functions implemented in libm. One potential problem on HP-UX 10.20
is that these will return incorrect results if passed floats instead of doubles,
and if the preprocessor flag HPUX_SOURCE is not specified. However, most
HP-UX sites should be using the proper flags, and it's a non-issue with HP-UX 11.
