Hm, I suppose that's true as far as the linker goes.  It is not true as
far as the include files go, and I consider them part of libc; they
describe the interface, and when you add something to libc you add it
to an include file too in some large subset of the cases (certainly the
ones where it's intended to be user-visible).

If you add something to libc and never add it to any include files
anywhere you may be right.  But, for example, heapsort showed up in
some include file which most of those heapsort-using programs of mine
included, and they broke at compile time as a result.  One reason - a
minor one, but still one - I'm not tracking current NetBSD at home is
that I don't need the pain of repeating the heapsort exercise every
time NetBSD thinks some common name should be dropped into some
heavily-used include file, thereby breaking all of my code which uses
that name for its own purposes.  (Well, most - all that also uses the
affected include file.)
