Subject: [Caml-list] Compiling with camlp4 extensions

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
