commit 64bbe4248f8b194a6a8d620c477744f702d1781b
Author: Bob Paddock <bobpspam@xxxxxxxxx>
Commit: DJ Delorie <dj@xxxxxxxxxxx>

    Use rand() in place of random().
    
    The 'random', 'srandom', functions are those from BSD derived UNIX's,
    and may not be available under WIN32.  The 'rand' and 'srand'
    functions are required by the ANSI standard.
    
    rand(): Return a random integer between 0 and RAND_MAX inclusive.
    random(): Return a random long integer between 0 and RAND_MAX inclusive.
    
    Standard MinGW stdlib.h only supports rand() and RAND_MAX is limited
    to the 32 bit value of 32767, which is significantly smaller than that
    returned by random().  This turncation of range should not effect
    usage in our application.
    
    Added srand( time(NULL) ) to main.c to set the seed.
