It makes sense to use C99 functions internally where it's possible to
do that without breaking C89 compatibility, by providing portable

isfinite(), but there are other cases that could be changed.

Hi Brian:

I'm glad that you brought up isfinite().  I have never been able to
get this C99 feature to work with gcc.  Is there some magic trick here?
This is for relatively recent gcc (v. 4.x) on both Mac OS X and Solaris.
I must be doing something wrong, but I can't seem to figure it out. There must be some clues in GSL somewhere. Any hints?
