I must be missing something.

I've looked at the UPDATING doc and:

* updated my ENTIRE source tree.  From scratch.  Twice.
* make obj
* reinstalled the .mk files
* rebuilt yacc and make
* rebuilt the rest of the toolchain (-DNOMAN -DNOPIC, since there is no
  manpage for collect2).

Aside from ncurses not compiling and libc++ not working for me (hence my
motivation to recompile the entire world), It bombs out in building sh
thus (forgive the long lines):

cc -O2 -O3 -pipe  -Wall -Wstrict-prototypes -Wmissing-prototypes -Wpointer-arith -Wno-uninitialized -Wreturn-type -Wcast-qual -Wpointer-arith -Wwrite-strings -Wswitch -Wshadow -Werror    -o mkinit /usr/src/bin/sh/mkinit.c
