At 160kbs, the compression ratio is 8.8 (and it is printed
correctly by both your lamei and lamem)  Here's the code in
lame which disables jstereo if compression_ratio < 9
(from lame.c):

  /* At higher quality (lower compression) use STEREO instead of JSTEREO.
   * (unless the user explicitly specified a mode ) */
  if ( (!gfp->mode_fixed) && (gfp->mode !=MPG_MD_MONO)) {
    if (compression_ratio < 9 ) {
      gfp->mode = MPG_MD_STEREO;
    }
  }

Is it possible the intel compiler doesn't like comparing a float with an int?
Can you try changing the if statement to:

   if (compression_ratio < 9.0) {

?

Thanks,
Mark
