Intel. Altos. Unisys. UnixWare. Basically any IBCS2 compliant UNIX, since they follow the standard, and the standard mandates shared library compatability if chared libraries are supported. And this is just Intel UNIX. There's also DGUX, Sanyo/ICON, Motorolla, Gould, and any other member of 88Open that uses Motorolla 88k processers. There Arete and NCR and Unisys and Motorolla for 680x0 (x = {2,3}). To those of you who are about to argue that Unisys and NCR are the same machines, you have apparently never tried to write a tape driver. To those of you who would claim Unisys' licence of SVR4 to be vanilla, you have apparently never tried to write a multithreaded file system. To not maintain binary compatability *including* shared images would be folly. People keep saying that "Linux is just as fragmented as BSD" when BSD is attacked for two distributions (for the free variety). But I have never heard of a binary compatability problem between say Slackware and Yggdrasil.
