Marshal module.

Marshal module.

[Ken Wakita]

Hi,

Using the Marshal module from the ocaml interpreter, I found its strange
behavior.  Though Marshal.from_string is registered in the Marshal.mli
interface file, the interpreter complains for "Reference to undefined
global".  Folloing is my session

Add "marshal" to 

PERVASIVES=arg array callback char digest filename format gc hashtbl \
  lexing list map obj parsing pervasives printexc printf queue random \
  set sort stack string stream sys oo genlex topdirs toploop weak lazy

in the main Makefile.

Yes, that's a mistake in the building of ocaml.  Basically, the
implementation of the "Marshal" module was removed.  The reason you
can still use "Marshal.to_string" is that it's a primitive, not
defined in the implementation of "Marshal", while "Marshal.from_string"
is ML code from the implementation of "Marshal".

The problem will be fixed shortly.  Thanks for the bug report, but
really your message doesn't belong to caml-list@inria.fr, you should
have mailed caml-light@inria.fr instead.
