Hi, I have been trying to use the new camlp4 to write an OCaml syntax extension. All the examples I have seen so far suggest that I use the extension by passing ocamlc the "-pp" option. But it seems that all the location info for error messages gets lost when I do this unless I catch and report the parse error myself within the extension. Is there some way to get ocamlc to report the parse error at the correct location automatically? - Aaron
