(In reply to Mark Millard from comment #15)

I have to agree fully and I think this topic has been hammered down
neatly with nothing further needs to be said. 

You say "I find no evidence that posix requires the kind of
interpretation you are expecting" and I must fully agree here. There
really is no statement from the OpenGroup et. al. which would claim
that the uname struct members need be anything portable or even dare
I say it "standards conforming". 

I know that I hand waving around "cannot be used portably" without
the real detailed digging that you have done. 

With regards to uname() I must agree that "FreeBSD is not violating
POSIX via FreeBSD's behavior" entirely. 

This means that I will need to wrap some code in "ifdef" stuff and then
drag out sysctl and friends. I will begin work on that immediately and
also cease and desist the usage of uname() everywhere else. It may work
on NetBSD and Solaris systems but we now know there is no such promise
across multiple implementations. Such is the state of affairs.

To echo Warner Losh in full hand waving "wow let's stop this now" 
because : 

    "Yea, POSIX doesn't say what the values mean, so anything we
    return is standard conforming, so therefore we're standards
    compliant.

    It might not be useful, but it is standards compliant. :)"

Yea verily I say unto you all :

I would like to close this as "Not a Bug" with "It never was anyways!"
