Yes, Autoconf is very bloated in this regard.  Those extra tests aren't 
specified by us in configure.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.
