I don't mean to be an ass, but do you read before you mouth off? Judging by
the fedora-* list traffic, no. Let's try again:
1003.1-2001. For example, if you have a newer system but are running
software that assumes an older version of POSIX and uses `sort +1' or
`tail +10', you can work around any compatibility problems by setting
`_POSIX2_VERSION=199209' in your environment.
Sorry, I'm cranky. Now I have to go put a wrapper around coreutils and
log old-style arguments.
Environment variable tests are completely broken. That was already known
in the 1970's ... but I gave up on POSIX when I was a reviewer for the
pthreads drafts ...
