The ToDo section should probably look like this:

        {
            int const sbitval = pm_maxvaltobits(MIN(maxval, pngMaxval));
            png_color_8 sbit;

            if (png_get_color_type(pngP, pngInfoP) & PNG_COLOR_MASK_COLOR) {
                sbit.red   = sbitval;
                sbit.green = sbitval;
                sbit.blue  = sbitval;
            } else
                sbit.gray = sbitval;
            
            if (verbose)
                pm_message("Writing sBIT chunk with bits = %d", sbitval);

            if (png_get_color_type(pngP, pngInfoP) & PNG_COLOR_MASK_ALPHA) {
                sbit.alpha =
                    pm_maxvaltobits(MIN(alphaMaxval, pngMaxval));
                if (verbose)
                    pm_message("  alpha bits = %d", sbit.alpha);
            }
            png_set_sBIT(pngP, pngInfoP, &sbit);
        }

        Kind regards
