I cannot reproduce this: w32term.c compiles for me just fine.  And the
error message looks very strange anyway, since w32term.c has only 6474
lines (and was last modified on 5th June, so if there were a problem,
lots of people would have complained by now).

Can you see what is going on around the lines that GCC complains

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

$ 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.
