+Summary: Different, maybe wrong, number in Random.cs implementation
+
+In line number 77 of [mono]/mcs/class/corlib/System/Random.cs we see      
+                  "inextp = 21" while if we check "Numerical Recipes in C
+online @ http://www.library.cornell.edu/nr/bookcpdf/c7-1.pdf" we see it
+must be "inextp = 31" because "the constant 31 is special; see Knuth".
+
+Although I don't know why it's needed a 31 instead of a 21 I don't see any
+reason to change the number. Maybe the Random class mus be reviewed by its
+author to check it hasn't any more subtle "bugs".
