I am hardly an automake expert. I don't know how automake decides
when to generate a rule. I don't know why itbl-parse.[ch] doesn't
have the same problem. The obvious difference is that I see
itbl-parse.c and itbl-parse.h, but I see bfin-parse.c and
bfin-parse.tab.h. Perhaps if you change bfin-parse.tab.h to
bfin-parse.h automake will recognize what is going on.
