The gcc warning can be turned off by adding a /* fall through */ comment at the point the fall through happens (assuming that the fall through is intentional). --=20 Cheers, Stephen Rothwell --Sig_/P/3Nxd.XblUEf2RjQpecfHe Content-Type: application/pgp-signature Content-Description: OpenPGP digital signature -----BEGIN PGP SIGNATURE----- iQEzBAEBCAAdFiEENIC96giZ81tWdLgKAVBC80lX0GwFAlyikO8ACgkQAVBC80lX 0GzPiwf/RsxhnQrKYYUV4DYpBXGK70zlPEcW1Bdz8Wmom/nfLea2LnqUgbmPa3Yl dXWMtEB7pN+ApkeNqDJYGRUQmgYg2TyKE03JuIaGGZiOMauIGsjxY77pcd9C8AHo bN6KIKjYItL+K7uzjaq8nCSS9rfU+HXvp0/olGxjRt1fqZKxixWOVfWAL+V+xJRE zO1p6x9+Us/17Ye8SYRp/RISWWpYeXOIW5C7ouhACj2pYYw2blgcxgkk8Ss/ga7f qmlfRYb5ERNKdKGvzN9BWP2EipZH69rT2mV7v0NHdELj/lTLYsjaFkJPUb2KDVU2 yNLW5UsQ7I2qyRd/ESK702j+liouMQ== =E5eg -----END PGP SIGNATURE----- --Sig_/P/3Nxd.XblUEf2RjQpecfHe--
