Yes finite() is obsolete on many systems, however isfinite() is only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.

I’m trying to compile GSL with Xcode 5.02 (clang) on Mavericks for iosphoneos

Examination of
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator7.0.sdk/usr/include/math.h
shows:
/* Legacy BSD API: please use C99 isfinite( ) instead. */
extern int finite(double) __OSX_AVAILABLE_BUT_DEPRECATED(__MAC_10_0,
__MAC_10_9, __IPHONE_NA, __IPHONE_NA);
I understand what it wants me to do, and it seems GSL is slowly moving from
finite to infinite, but this process isn’t complete. Can this be addressed?
