This commit had zero effect as RAND_MAX is actually defined as 2^31-1, it is 
just a pedantic fixup of the previous revision (1.18) which changed random(6) 
from using LONG_MAX as the maximum value.  Using LONG_MAX mean that random(6) 
always selected zero lines from an input file on 64-bit archs such as amd64.  
The previous revision's log has an associated PR with more details.
