Much simpler is just add

if (ARRAY_SIZE() == 0)
 return;

-       for (i = 0; i < ARRAY_SIZE(feature_properties); ++i, ++fp) {
+       for (; fp != feature_properties + ARRAY_SIZE(feature_properties); ++fp) {

...or convert to while(), which will be more readable.

So you'd prefer something like:

while (fp < feature_properties + ARRAY_SIZE(feature_properties)) {
  ...
  ++fp;
}

right ?
