Do not use srand()/rand() if better alternatives exist (mirabilos)
arc4random(3) is a self-seeding PRNG available on a lot of OSes (all BSDs,
Darwin / Mac OSX, Interix / Microsoft® Services for Unix, Windows® 2003SR1,
Windows® Vista, Debian with the new libbsd package installed, ???) and much
better than srand(3)/rand(3).
Thanks to GNU autoconf, this can be made portable.
