Given any "UNIX", an expert can find a POSIX violation beyond an extension. z/OS is the only UNIX I know that doesn't commit POSIX the vi fencepost violations. And z/OS fails "cd -P". But that's merely a violation by anachronism.
All in all, it's easy to move among z/OS, Solaris, OS X, Linux, Cygwin, ... It would be different if POSIX demanded ASCII, which it should, but doesn't. -- gil
