Subject: [Caml-list] ocamlbuild / menhir with --infer / ocamlc options other
 than -I

Hi,

I have a parser that opens a module compiled with -rectypes. Although I 
added the rectypes tags (true: rectypes) to my ocamlbuild configuration, 
ocamlbuild does not add the -rectypes flag to the --ocamlc command given 
to menhir.

 From the source code (ocaml_tools.menhir), it seems that only the 
include flags are passed to the --ocamlc command:

   Cmd(S[menhir;
         A"--ocamlc"; Quote(S[!Options.ocamlc; ocaml_include_flags mly]);
         T(tags_of_pathname mly++"ocaml"++"parser"++"menhir");
         A"--infer"; Px mly])

Bests,
     Pierre-Yves.
