* configure.ac: Remove -with-acl option, since Gnulib does that for us now. (LIBACL_LIBS): Remove; no longer needed. * lib/Makefile.am (CLEANFILES, SUFFIXES): New (empty) macros, for the benefit of the new ACL implementation. * lib/makefile.w32-in (GNULIBOBJS): Add $(BLD)/acl-errno-valid.$(O). ($(BLD)/acl-errno-valid.$(O)): New rule. * lib/acl-errno-valid.c, lib/acl-internal.h, lib/acl.h: * lib/acl_entries.c, lib/errno.in.h, lib/file-has-acl.c: * lib/qcopy-acl.c, lib/qset-acl.c, m4/acl.m4, m4/errno_h.m4: New files, taken from gnulib. * lib/gnulib.mk, m4/gnulib-comp.m4: Regenerate. * admin/merge-gnulib (GNULIB_MODULES): Add qacl. (GNULIB_TOOL_FLAGS): Do not avoid errno. * etc/NEWS: Emacs is no longer limited to POSIX ACLs. --disable-acl, not --without-acl, since we're now using Gnulib's implementation. * nt/config.nt (HAVE_ACL_SET_FILE): Rename from HAVE_POSIX_ACL. * nt/inc/ms-w32.h (EOPNOTSUPP): New macro. * src/Makefile.in (LIB_ACL): New macro. (LIBACL_LIBS): Remove. (LIBES): Use LIB_ACL, not LIBACL_LIBS. * src/fileio.c: Include <acl.h>. Use HAVE_ACL_SET_FILE rather than HAVE_POSIX_ACL. (ACL_NOT_WELL_SUPPORTED): Remove. All uses replaced by !acl_errno_valid. (Fcopy_file) [!WINDOWSNT]: Use qcopy_acl instead of rolling it ourselves. Fixes: debbugs:14295
