There's something about automake 1.13 which breaks use of patsubst /
subst (or any GNU make extension used in certain automake variables).

I can't test if it will specifically break this because I don't have
access to any machines that don't have ocamlopt, but it's something to
watch out for.

In any case, I have pushed this since it works fine for me.

Something for the future: It'd be nice to use automake to build
objects.  This is possible if the program contains at least one C
object file.  See:

Thanks,

Rich.
