I didn't say this. POSIX doesn't define these values.

So you didn't really read my initial email properly.
Unless someone stumps up the time to change git, then that application
will never work. Python was an easy fix. There may be other applications
out there too, who knows. But until you actually bump into the problem
and go hunting it can be a needle in a haystack.
If we change (and I'm not saying need to), then application level fixing
and therefore manpower on fixing other applications would be a zero
effort for making the changes to the kernel.
And obviously Helmut has noticed your overly negative attitude towards
the thread. And as I've mentioned before, I'll leave it for now and
gather any more applications I bump into.
I'm not spending any more time on this thread.
