A long, long, time ago, on a newsgroup far, far, away, a guy called
Bob Jenkins and I had a discussion about good random number generators
(cryptographically secure ones, in fact), with the result that I have
a tarted up version of his RNG called ISAAC on my web page at
"http://www.abwillms.demon.co.uk/crypto/".

It compiles fine under DJGPP, 'coz that's what I used.

More info can be got from
