+ file-has-acl: Split feature tests again (Bug#20667)
+ * lib/file-has-acl.c: Instead of testing for
+ XATTR_NAME_POSIX_ACL_ACCESS and XATTR_NAME_POSIX_ACL_DEFAULT,
+ define them when needed.
+ * m4/acl.m4 (gl_FILE_HAS_ACL): With that, Paul's
+ GETXATTR_WITH_POSIX_ACLS change shouldn't be needed anymore.
