Hi, Luis
I think you should keep this change, because it really works.
Before this change, the IOlib project [1] cannot be compiled by 32-bit LispWorks, because some UNIX system calls are taken 64bit integers as arguments. Now with your change, IOlib can be compiled & loaded correctly on 32-bit LispWorks.

Chun Tian (binghe)

Sorry for the late response.
I don't have the code/opportunity to test all the cases; but wonder if the enclosed patch - touching all the #+lispworks-64bit, is what's really needed. . . ?
Well, could you tell me whether my previous patch works for you and why you need this one?
I.e. every 64-bit replaced with (or lispworks5.1 lispworks-64bit) or the like

The long-long gets through and fails in the lispworks-specific "Ecase" (that has them removed for non-64-bit lispworks).
Long-long emulation is not implemented for DEFCFUN, DEFCALLBACK, etc. It turns out that Lispworks does in fact support long-long on 32-bit platforms for DEFCFUN at least. Please let me know if the attached patch works for you.
