Message:
I found another bug, which didn't show up in statistical tests. The
unloaded file contains GSL implementation and Matlab file used to generate
look up tables. For some strange reason GSL implementation uses different
value for the right-most step. My implementation uses the same value as
reported in Marsaglia and Tsang (2000). If you use GSL value in the matlab
file, it fails the diagnostics step.
