You have shown that the proposed change does not violate either standard.
Therefore it is legal to make the change.

Make that: Solaris, IRIX, Digital UNIX, and AIX. (basically every UNIX)
Considering the above, portable UNIX apps may indeed expect a useful
return value.

Are we a UNIX clone or a BSD clone?
I see a perfectly good Free Software version of BSD. Actually, there
are three of them. I don't see a good Free Software version of UNIX.
It would be pretty stupid to clone existing Free Software. If I want
to get BSD behavior, duh, I might just get the real thing!

Fine, Debian has a way to automatically apply patches. This is a good
patch. It makes it easier to port UNIX code to Linux.
