confstr() should return 0, not -1, on errors
confstr() should return 0, not (size_t)-1, on errors. The current
DragonFly BSD implementation returns -1 if sysctl() fails.

Not with top-of-tree FreeBSD, it isn't - the top-of-tree FreeBSD code
The documentation, until recently, said it returned -1, but I filed a
bug about that:
and it was recently fixed:
As for NetBSD, I filed a bug on the code:
which is now closed - they changed the code and the man page.
Similar changes were made to OpenBSD in response to bug mail I sent:
so DragonFly is now inconsistent with the top of the tree of FreeBSD,
NetBSD, and OpenBSD, and its code is inconsistent with the 5.x and 6.x
releases of FreeBSD.

Perhaps POSIX.2 said it returned -1 (I think my POSIX.2 is at work), but
what counts now is the Single UNIX Specification, and, as per the URL I
think I sent in my mail:
it says it returns 0 on errors.

Seems pretty conclusive to me. Would someone like to make this
adjustment in our tree?
