Boar's Resilience / Improved Stalwart, Natural Weapons

[Xathris]

Does Boar's Resilience count as Endurance to qualify for Improved Stalwart?

"You are unimpaired by being at exactly 0 hit points. In addition, you can ignore the Endurance prerequisite for the Diehard feat."

Can you ignore it for Improved Stalwart?

Also, if a wereboar has 2 hooves, a gore attack (extra features) a bite attack, and 2 claw attacks (rage powers), does he get 6 attacks at full BAB?

Thanks!

Just found out that the hooves would be secondary (rules). Haven't found out about Boar resilience yet.

You ignore it for Diehard. That’s it. You still need it for any other feat or ability that requires it.
