Is there anyway to control the behavior of ylwrap? The project I am converting has its parsers use files like foo.l and foo.y for the lex and yacc files as they go together, and automake then converts both of these to foo.c, overwriting the first seemingly silently. Admittedly I solved this by changing foo.l to foo-lex.l, but it seems rather inelegant. If there is a to notice the existence of foo.l and foo.y in the same directory, it might be worth printing out a message as it is not an immediately obvious problem (except for refusing to build).
