Yes, Autoconf is very bloated in this regard. Those extra tests aren't specified by us in, they're just what Autoconf does.

Also, autoconf is doing them twice. Once when you type ./configure and once again when you type "make." I'm not sure why it has that behavior. Possibly it is due to BUILT_SOURCES, but I do think chicken-defaults.h has to get built before other stuff. If one is motivated, one could experiment with whether there's a better way to specify the chicken-defaults.h dependency. What I have in Darcs works though, and I won't be prioritizing such things from here on out. I'm not interested in sitting around perfecting the Autoconf build. I'd rather that energy go to the CMake build, or to new features.
