     After unpacking, compiling and studying the compiler "warning" messages
I've got Zoo - version 2.01 up and running on Sun 3's, 4's and 386i's running 
SunOS 3.4, 3.5 and 4.0. 

     Executing the 'mkbsd' script worked perfectly under SunOS 3.4 and 3.5, 
but the compiler complained of

                 warning: illegal pointer combination

under 4.0. The problem simply turned out to be, that the value returned from
signal() under pre-4.0 was a pointer to an int. Under 4.0 it is now a pointer
to a void.  The fix is (take your choice):

1) Ignore the compiler warnings. The executable works perfectly dispite the
   warning messages (though I did get an e-mail message that his may not be 
   correct on a Sun 4).

     -- or --

2) Redefine the oldsignal declaration in comment.c, misc.c (2 declarations),
   zoodel.c, zooext.c, and zoopack.c from:

   int (*oldsignal)();

       -- to --

   void (*oldsignal)();


     Thats all folks!!
