Hi -
I just tried to load the latest CFFI from darcs into CCL 1.2, and I
got a symbol conflict between CCL:COPY-FILE and ALEXANDRIA.0.DEV:COPY-
FILE:

When I look in the CFFI code, the problem seems to come from cffi--
openmcl.lisp where ALEXANDRIA and CCL are both being :use-d without
any shadowing. As far as I can tell, there are no calls to either
COPY-FILE function anywhere in the CFFI code, so it seems to me that
choosing one of these functions to shadow the other should be a
simple affair since it shouldn't matter at all which one is chosen..
Would it be possible to get this fixed?
Thanks.
Dan
