OK. Is there a simple way to detect whether the :if-exists :overwrite option is available? If I try to use it on my Ubuntu 12.04.3 LTS's "GNU CLISP 2.49 (2010-07-07)", I get:
(posix:copy-file "/tmp/b" "/tmp/c" :method :rename :if-exists :overwrite)
*** - EVAL/APPLY: Too many arguments (4 instead of at most 2) given to RENAME-FILE
