   Chris Hanson came up with a (quick!) pointer to the source of
the trouble. For the benefit of any R6.1.x users, the file "mul.c" has
a declaration:

   fast long Hi_A, Hi_B, Lo_A, Lo_B, Lo_C, Middle_C;

which should be modified to:

   fast long Hi_A, Hi_B, Lo_A, Lo_B, Middle_C;
   fast unsigned long Lo_C;

This certainly fixed this on our 370, and I suspect, from what I know of
the 68000 multiply (which also produces a result in which the low-half is 
effectively "unsigned") should fix the Sun-3 as well. 
   I also understand that this has been "fixed in Release 7".
   Many thanks to all who responded.

PS: It Definitely fixes the problem on the Sun-3 -- I just saw it.
