np.  i've been a bit unhappy with the build in general and it detecting
changes.  i'm hoping the move to automake will help more with that, and
with getting more knobs out of CPPFLAGS and into config.h (or doing it
at runtime).

i've gotten a bit in the habit of doing `make clean` and leaning on ccache
to keep rebuilds fast.
