What about we simplify this a bit:

    if (lf.lfUnderline || lf.lfStrikeOut) {
        long linePos = (lf.lfUnderline ? tm.tmDescent / 2 : - tm.tmAscent / 3.5);

        TSXSetForeground( gdi_display, physDev->gc, physDev->textPixel );
        TSXSetLineAttributes( gdi_display, physDev->gc, lineWidth,
                              LineSolid, CapProjecting, JoinBevel );
        TSXDrawLine( gdi_display, physDev->drawable, physDev->gc,
                     physDev->org.x + x, physDev->org.y + y + linePos,
                     physDev->org.x + x + width, physDev->org.y + y + linePos );
    }
