Yes, that's right.  This is not a problem, as 99% of Wine users on NetBSD
are building from source.  The very small remainder of prebuilt-binary users
can easily be told to ensure that the OS version is up-to-date (since there
are security fixes that necessitate this anyway).

You have to bend over backwards to do the runtime check, and you sacrifice
*maintainability* with the extra normally-dead code added to Wine.  I don't
see a need to jump through extra hoops in this case.
