Absolutely correct. The kernel defines the interface, libc just
uses it.

Well, you might remember some conversation we had about libc
symbol names some months ago... Consequently, we should allow
(or better require for the future) libc minor version numbers
for renames of libc outer interfaces.

I believe I've proposed this too a while ago. I'd appreciate it, would
make maintainance a lot easier.

It seems that the renaming business is a major PITA for 3rd party
users. While this serves its purpose for compatibility, and thus is
needed for regular releases, it would be nice to be able to switch
off by a single "make" option.
