We had two almost-identical copies of the utility function clause_sides_match_join() -- one in joinpath.c, and one in analyzejoins.c. Both copies were marked "inline," so we might as well just move the (inline) function definition into a common header file. I chose pathnode.h, because it is already #included by both of the .c files.
This change doesn't help very much, on its own (since the almost-duplicate functions are both "inline"), but it allows us to use the same utility function from other source files, without making a third copy. James
