Re: Emacs 21.3.50 grep.el/executable.el problems

[Richard Stallman]

    Great, so now grep-find works again.  In fact, it tells that there is
    another use of executable-command-find-posix-p, namely in
    filecache.el.  Maybe one should change that as well and then remove
    executable-command-find-posix-p.

Someone said that filecache.el previously failed entirely to cope with
a nonstandard find, so perhaps we lose nothing by leaving it in
and we may as well fix it instead.
