Thanks for the fast response.
But ocaml/stdlib/sys.c contains this function:

CAMLprim value caml_sys_getenv(value var)
{
  char * res;

  res = getenv(String_val(var));
  if (res == 0) caml_raise_not_found();
  return caml_copy_string(res);
}

I found out that it is a links problem because of mixing a 
static library and a DLL.

best regards,
Christoph Bauer
