I don't have a windows box handy; if I did I would try:

in gui-win32/screen.c change the calls to GetDeviceCaps
to SystemParametersInfo with SPI_GETWORKAREA parameter. something like:

RECT ds; // size of work area in primary display
if( SystemParametersInfo(SPI_GETWORKAREA, 0, &ds, 0) ){
  dx = ds.right - ds.left;
  dy = ds.bottom - ds.top;
}
