Excellent!

Actually, this is coming from my linked list code - this is probably
the first it's been compiled on a 64-bit platform.  Honestly, I cannot
remember the purpose of that check.  You can probably remove the code
that checks for that in lists.c, function 'lcreate()' and also remove
the #define LISTSZ from lists.h.  I don't see anywehre else that it is
referenced.

The only thing I can think of is that I must have had an application
that used the linked list routines and I needed the size of the LIST
elemement, probably for an array of them or something, but I did not
want to expose the actual data structure, so I used that hard-coded
size instead.  The size there looks like it might be the size of a
pointer on the platform it is being compiled on?

At any rate, I think you can safely remove the #define and the check
and it should still work fine.
