Hello, Another concern of the original post was how to handle anonymous C enums in cffi.
Should one use `defconstants' for them? Or should cffi provide a mechanism to declare anonymous enums?
As per my understanding cffi requires all enums to be named.

I don't really think of C's enum that way. If I want constants, I use #define (and defconstant in CL). If I want to represent some sort of entity or concept I use an enum (and symbols in CL). For example:
#define MAX_COUNT 127
(defconstant +max-count+ 127)
vs.
enum { RED, BLUE };
:red, :blue (or 'red, 'blue)
I suppose defcenum shouldn't force the user to use keywords though?
