You need to call `srandom' with a different seed in order to get a 
different series of random numbers.  The usual trick is to pass the 
current system clock as the seed.  See section 22.22 in the DJGPP FAQ 
for more details.

Also, `srandom' goes with `random', not with `rand'.  If you need to 
randomize the series returned by `rand', use `srand' instead of 
`srandom'.
