Polis Crushers has Protection from Enchanted Creatures?

Matt attacks with his Hero of Iroas 

enchanted with a Mogis's Warhound

which Andrew blocks with his Polis Crusher

Does the Polis Crusher take 4 and die OR does the Polis Crusher have protection from the Enchanted Hercules and take no damage?

This question appears to be answered by the Gatherer:

• 9/15/2013: “Protection from enchantments” means that Polis Crusher can’t be enchanted, it can’t be targeted by Aura spells or by abilities of enchantments, all damage that would be dealt to it by enchantments is prevented, and it can’t be blocked by enchantment creatures. Notably, it doesn’t have protection from enchanted creatures (unless those creatures are also enchantments).
