were recently), a simple 'make cleandepend; make depend' is sufficient
to keep the tree buildable after a cvs update when doing incremental
builds.
However, kdump and truss use a script which searches for header files
that define ioctls, and generates C code that includes them. This
script will usually not need updating when a header file is removed,
so the normal dependency mechanism will not realize that it needs to
be re-run. One is therefore left with code that references dead files
but will only be removed by a full 'make clean', which defeats the
purpose of incremental builds.
To work around this, modify the cleandepend target in bsd.dep.mk to
also remove any files listed in a new variable named CLEANDEPFILES,
and modify kdump's and truss's Makefiles accordingly.

David wanted to implement the suggestions which came up at the review from
arch@ too, but real life rejected this proposal. So I commit what we already
got and let another volunteer pick the remaining work from the ideas list.

breakage with ioctl.c. The .depend file should track dependencies
just fine, and the worst we can have is to miss new ioctls.
But I still think it's a good idea to have -DNOCLEAN build produce
the same ioctl.c as it would without -DNOCLEAN.

controls whether a switch-statement is to be used instead of a series
