ANSI C says that `rand' will always generate the same sequence if `srand' 
is not called before the first call to `rand'.  It also specifies that 
the above default sequence should be the same as if `srand' was called 
with a seed value of 1.  This means that the DJGPP implementation does 
not conform to this last requirement, since it generates a sequence as if 
`srand' was called with a seed of 0.
