Each target language should working with just the std_string.i library file:

%include <std_string.i>

I don't know what the state of Ocaml is in this respect though, but 
there are typemaps in this file. I don't know what you mean they are 
never used, as the test-suite uses this file in a number of places. It 
could well be the case that they don't work as no-one is maintaining or 
testing Ocaml.

The typemaps/std_string.swg file has only been used by a subset of 
scripting languages. Usually a target language will convert to using all 
of the UTL (Unified Typemap Library) typemaps in the typemaps directory 
or none at all. I don't believe Ocaml uses any of the UTL at the moment, 
so I think your best bet is to avoid the UTL for a quick fix and fix 
what is in Lib/ocaml/std_string.i.
