Hmmm....I've now compared snapshots 060210 through 060215 in
progressive stages and identified the folowing differences:

The delta between 060210 and 060213 is:

src/foreign-vars.lisp
src/functions.lisp
src/package.lisp
src/types.lisp
[plus test file differences]

The delta from 060213 to 060214 is:

src/cffi-allegro.lisp
src/cffi-openmcl.lisp
src/cffi-sbcl.lisp
[plus test file differences]

And from 060214 to 060215 we have:

src/cffi-lispworks.lisp
src/package.lisp
src/types.lisp
[plus doc and test file differences]

The changes in 060215's version of cffi-lispworks.lisp are
that the following have been added:

defun convert-foreign-typed-aref-type
defun pointer-and-index
compiler macros for %mem-ref and %mem-set

Hopefully this code spelunking can help track down what's
happened :-)
