The easiest way to build interfaces in recent versions of the lisp
(since last summer sometime) is
? (create-interfaces :libc) ; or :quartz, or whatever.
That'll run the FFI translator, then run PARSE-FFI twice; the
second pass is sometimes necessary to deal with things like
#define x y
#define y ...
The plan is to use svn (instead of cvs) in the next release (soon,
working on it); that has the nice benefit of allowing you to do
shell> svn revert ...
when you clobber something.
(The cost involves keeping redundant copies of everything in the
working directory, but that (disk space/bandwidth) may be minor
compared to "just hosed my image and no easy way to boostrap one.")
