posted this to the coreutils a list sometime ago ... idea is to be able to disable automatic ACL detection via --disable-acl since this can often times take the form of an external library rather than part of the system libc.
patch was originally written/tested against coreutils-6.9 and ive forward ported it to current gnulib git. -mike
