For 3.14 we already have epicsMath.h which defines epicsIsNAN.
I added a definition for epicsIsINF.


Before INF we only needed to provide epicsMath.h in

osi/os/posix
osi/os/WIN32
osi/os/vxWorks

For epicsIsINF I had to add

osi/os/solaris.


In order to make 3.13 more4 similar to 3.14, I will add  epicsMath.h to

<base3_13>/src/libCom/os/*

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?


Also it would be nicer if we could use the names isnan and isinf instead of 
epicsIsNAN and epicsIsINF but code that uses these must include something in 
addition to math.h in order to be OSI independent.


I suggest the following:


Code that uses them must include epicsMath.h. The names will be isnan and isinf.


Any objections?
