I ... think CFFI should support LispWorks 5.0 for long-long, because  
5.0 (64-bit) do support it and not every 5.0 user can upgrade to 5.1  
(new license and money is required). And (I think) LispWorks will  
continue support 5.0 by release new patches in the future. For me, I'm  
using both 5.0 and 5.1 right now. Without long-long support, it is  
impossible to compile IOLIB on LispWorks 64-bit 5.0.

Since it's not hard to consider both versions, I (personal) hope you  
can support them both, and that will be perfect.
