Recently copy-file was augmented to add support for
copying ACLs on abandoned-POSIX-style hosts.  Here's
an additional patch to add support for copying ACLs on
Solaris, HP-UX, etc.  Basically, the idea is to use
Gnulib's support for ACLs.  I've tested this on
GNU/Linux and Solaris, but not on Microsoft platforms,
and am CC'ing this to Eli as a heads-up for that.

This changes the 'configure' option from --without-acl to
--disable-acl if one wishes to disable ACL support when
configuring Emacs; this is the option spelling that other GNU
packages use.
