  Log:
  Rev 1.132 was backed out because of the following from BDE:
  
          By returning garbage for the unused high bits of segment registers, we
          avoid wasting time initializing the bits if the results are assigned to
          32-bit variables.  movl instead of movw was also intentional, to
          prevent gas adding pessimal pessimal segment overrides.
  
  See src-committers Message-ID: <20030419173421.N15436 at gamplex.bde.org>, for
  more details and how to optimize this farther.
