made the test-program in the bottom compile/build, remember to link with

  form=Curl_getFormData(httppost, &size);

  FormInit(&formread, form);

  Curl_FormInit(&formread, form);

  while(nread = FormReader(buffer, 1, sizeof(buffer), (FILE *)&formread)) {

  do {

    nread = Curl_FormReader(buffer, 1, sizeof(buffer),

                            (FILE *)&formread);

    if(-1 == nread)

      break;

    fwrite(buffer, nread, 1, stderr);

  }

  } while(1);

  fprintf(stderr, "size: %d\n", size);
