Better make this

#else
  int w = priv->f->output_data.x->size_hints.min_width;
  if (minimum) *minimum = w;
  w = max (w, 800);
  if (natural) *natural = w;
#endif

and

#else
  int h = priv->f->output_data.x->size_hints.min_height;
  if (minimum) *minimum = h;
  h = max (h, 800);
  if (natural) *natural = h;
#endif

A comment in gtkwindow.c says

/* (Note: Replace "size" with "width" or "height". Also, the request
 * mode is honoured.)
 * For selecting the default window size, the following conditions
 * should hold (in order of importance):
 * - the size is not below the minimum size
 *   Windows cannot be resized below their minimum size, so we must
 *   ensure we don’t do that either.
 * - the size is not above the natural size
 *   It seems weird to allocate more than this in an initial guess.
 * - the size does not exceed that of a maximized window
 *   We want to see the whole window after all.
 *   (Note that this may not be possible to achieve due to imperfect
 *    information from the windowing system.)
 */

so if we make the natural size small, it's only natural that gtk chooses
a default size that is smaller than that.
