Dependencies in the Makefile are currently too broad brush. I don't enjoy waiting for everything to recompile every time I try to tweak the jit. The only file that #includes jit_struct.h is jit.c, so I feel that the Makefile dependencies should reflect this, and not cause a gratuitous recompile of everything. There are probably other auto-generated header files that world+dog should not depend on.
