Re: [Bug-gsl] finite deprecated in OSX, iOS

[Patrick Alken]

Yes finite() is obsolete on many systems, however isfinite() is only 
standardized by C99, not C89. GSL attempts to deal with this by defining 
gsl_finite() which is simply a wrapper to isfinite() if available, and 
otherwise finite(). The configure script tries to detect which (or both) 
are available.

I have replaced the last remaining finite() calls in the GSL code with 
gsl_finite() calls, so this should help if your system no longer defines 
finite().

Please see the latest git master branch for the changes.
