Compiling the ocaml fails:

Parsing tools/ocaml/libs/xl/../../../../tools/libxl/libxl.idl
sed: 1: "1i(*\
    * AUTO-GENERATED ...": command i expects \ followed by test
gmake[7]: Leaving directory `tools/ocaml/libs/xl'

I guess the sed script in tools/ocaml/libs/xl/Makefile has some
non-posix-ism in it.

Using gnu sed with --posix the following works for me (I dropped the
--posix). Does it help ?

I have to widthdraw my previous ack. The sed script didn't run because
of empty xm.ml and xm.mli files.

After running gmake dist-clean and recompile I get this error:

Parsing tools/ocaml/libs/xl/../../../../tools/libxl/libxl.idl
sed: 1: "1i\(*\
      * AUTO-GENERATED ...": extra characters after \ at the end of i command
gmake[7]: Leaving directory `tools/ocaml/libs/xl'

Can you play a bit with your version of sed and see what makes it happy?

Perhaps \n (suitable quoted) orjust a raw linefeed will work? If not
maybe just stick the whole autogenerated tag on a single line, or use
multiple i commands, or ....

I guess it wouldn't be the end of the world to do:
        echo "(* AUTO GEN... mummble etc *)">  xl.ml
        sed -e '/^(\* @@LIBXL_TYPES@@ \*)$$/r_libxl_types.ml.in'<bla>>xl.ml

With attached xen_tools_ocaml.diff  a xl.ml file is generated w/o
having sed complaining.
xl.mli is not generated at all.

I attached xl.ml. Can you check if this is the expected result, please?
