Wanted: random number generator written in C

[Kee Hinckley]

    Although it is probably not relevant in this case, I might
mention how the Apple ][ generates it's random number seed for
Applesoft Basic (although it is extensible to the Aztec C that
I use).  Quite simply, everytime it checks to see if a character
has been typed at the keyboard (which is everytime it prints a
character, or is waiting for input) it increments a counter.  That
counter then can be used as a reasonably random seed for any random
number generator that the user creates.
