I was under the impression that this build _was_ unoptimized (so I was
surprised to see those variables "optimized out").  I configured with

  $ ./configure --enable-checking --enable-check-lisp-object-type
--config-cache CFLAGS=-Og -g3

Maybe I should add -O0 to CFLAGS.  (I got those options from a recent
thread on emacs-devel about a proposed new file etc/DEBUG).

Yes.
