SUS is the standard to define UNIX. Even if they are identical, POSIX is needed for anything *nix., or *nix compatible. SUS must be fulfilled to even attempt getting called UNIX. If SUS didn't exist, than at minimum the UNIX trademark could be weakened. I'm not justifying any corporate action, just speculating on their position. | |

I'm still struggling to figure out the differences between ISO/IEC 10646 and Unicode which, while represent identical character sets kept strictly synchronized with each other are still two separate and different standards. I'm not sure why they can't just get along and declare them completely synonymous. | |
