dcdflib

[Clint Adams]

I get quite a bit of worrisome compiler output from the dcdflib stuff,
culminating in a failure.

I avoided the failure by applying this patch

http://www.freebsd.org/cgi/cvsweb.cgi/ports/math/dcdflib/files/patch-aa?rev=1.1.1.1&content-type=text/x-cvsweb-markup

over which I had to #include <limits.h> and <values.h>.

This left these warnings; can they be safely ignored?
