Use of C99 extra long double math functions after r236148

[Stephen Montgomery-Smith]

Hey guys, I just found this paper:

Implementing complex elementary functions using exception handling,
T. E. Hull, Thomas F. Fairgrieve, Ping-Tak Peter Tang
ACM Transactions on Mathematical Software, Volume 20 Issue 2, June 1994
Pages 215-244

This includes an algorithm for clog.  Now that I have discovered just 
how hard it really is, I am going to read this paper.

There is also a Corrigenda to this paper - the digital copy seems to be 
missing.  But I will try to retrieve the paper copy from my library.

If anyone else wants a copy of these papers, I would be glad to share 
it.  But I am using the University of Missouri subscription to ACM, and 
I don't want to abuse it by sharing the paper willy-nilly.
