Use AC_LIBSOURCES to list corresponding source (.c, .h, .y) files so that automake automatically knows to distribute those files. Use AC_LIBOBJ to ensure that automake automatically knows the names of always-compiled source files. Automake already knows the names of conditionally compiled ones, e.g., due to preexisting uses of AC_LIBOBJ and AC_REPLACE_FUNCS. [This is a start.
