Hi,

I've been trying to re-create the table in the function
"hypergeom_gain"
in preprocess.c, and I just simply can't get the same values. I get the
same value for the first element, so I know I'm computing gamma(1.25)^2
correctly, but I can't get the same numbers for M(-.25;1;-x), which I
assume is Kummer's function. Is it possible that the comment is out of
date and the values of Kummer's function used to make the table were
different? Any help would be greatly appreciated.
