>Description:
According to POSIX/SUS
(http://pubs.opengroup.org/onlinepubs/009695399/utilities/awk.html)

  srand([expr])
    Set the seed value for rand to expr or use the time of day if expr
    is omitted. The previous seed value shall be returned.

awk from NetBSD returns new seed, gawk and mawk work correctly.
