Thank you for the replies. In type_class.ml and type_class.mli, I
replaced (*pp cpp $ARCH_FLAGS *) with (*pp gcc -E $ARCH_FLAGS *). The
compilation gets further but now fails with:...
ocamlfind ocamlc -package type-conv -c -I +camlp4 -for-pack Bin_prot
binable.ml
File "binable.ml", line 36, characters 21-46:
Unbound type constructor Type_class.writer
