Both were part of POSIX. c89 was a strict ISO c89 compiler, while cc was c89, but could additionally accept "an unspecified dialect of the C language". http://pubs.opengroup.org/onlinepubs/007908799/xcu/cc.html So, if practicality isn't a good enough argument, maybe POSIX compliance is? ------enig2EAKHNPRBSMOOCFBNMNUT Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.19 (FreeBSD) iF4EAREIAAYFAlE5HMYACgkQfoCS2CCgtiua2wD/ebw/V5GCfriV7yeNOl8J0m+N pMyN4zAfZfeYvH48DXMA/jK5cI7iyXDpNIUU0bnpOJhcKOGIrZtTlnAKHTIsiKcm =TEYo -----END PGP SIGNATURE----- ------enig2EAKHNPRBSMOOCFBNMNUT--
