If we have a warning on that complains, we should turn it off. Well, bde@ considers it a style bug so from that point of view, the warning is useful. Also, given that the normal way of stating that is "#ifdef NOTYET", keeping the warning may help catch code where the preprocessor variable was supposed to have been defined but has been misspelt - consider "#if _FreeBSD_version > 800100". --=20 Peter Jeremy --Lb0e7rgc7IsuDeGj Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.15 (FreeBSD) iEYEARECAAYFAk1NO+8ACgkQ/opHv/APuIcR/QCeJmAdOeV8kG2u+bTgTkiBESGm jPQAoJ9RGexE1HSVesXs4OYdkzZKfTSe =aTK9 -----END PGP SIGNATURE----- --Lb0e7rgc7IsuDeGj--
