Re: EPICS on Mac OS X 10.5

Just adding the prototype is likely to just postpone the problem till  
link time (undefined symbol finite).  I think that it would be better  
to use the standard routine instead:
1) Find all references to finite and change them to isfinite.
2) For systems which provide finite() rather than isfinite(), add a  
macro to <os>/epicsMath.h defining the latter as the former.
