The lines around there are:

    /* Determine if Cleartype is in use.  Used to enable a hack in
       the char metric calculations which adds extra pixels to
       compensate for the "sub-pixels" that are not counted by the
       system APIs. */
    cleartype_active =
      SystemParametersInfo (SPI_GETFONTSMOOTHING, 0, &smoothing_enabled, 0)
      && smoothing_enabled
      && SystemParametersInfo (SPI_GETFONTSMOOTHINGTYPE, 0, &smoothing_type, 
0)
      && smoothing_type == FE_FONTSMOOTHINGCLEARTYPE;

I "grep"ed in src directory, the result is:

$ pwd
/cygdrive/e/emacs-cvs/src

$ grep -nR smoothing *
w32term.c:6551:      SystemParametersInfo (SPI_GETFONTSMOOTHING, 0, 
&smoothing_enabled, 0)
w32term.c:6552:      && smoothing_enabled
w32term.c:6553:      && SystemParametersInfo (SPI_GETFONTSMOOTHINGTYPE, 0, 
&smoothing_type, 0)
w32term.c:6554:      && smoothing_type == FE_FONTSMOOTHINGCLEARTYPE;

By the way, it's the Unicode 2 branch.
