Hi Till,

When building base-3-14-12-2-rc1 on uClibc
I found the following:

base is using 'finite()' which is a BSD routine
(and as such not available under uClibc).
OTOH, uClibc provides C99 and thus implements
the 'isfinite()' macro.

We already define finite() where the OS doesn't already provide it, see
src/libCom/osi/os/*/epicsMath.h.  Which OS class are you using for this
particular target?

linux. However, this is AFAIK a C-library std rather than an OS issue.
I'm using uClibc (which does not have BSD finite()).

Also it is odd that linux uses osi/os/posix/epicsMath.h but 'finite()'
is definitely not posix...
