Inherent bonuses and polymorphing

[Zaydos]

You're a fighter who read a Manual of Gainful Exercise +5 and your wizard friend casts Polymorph on you to turn you into an ogre (Str 21) would you have Str 26 (21 +5 Inherent) or Str 21?

Or more likely you're a druid who read a Manual of Gainful Exercise +5 and you wild-shape into a T-rex (Str 28) would you have 33 Str (28 +5 inherent) or 28 Str?

Gut instinct says you'd get the bonus.

About 90% sure this is RAW as well, but I can't back it up with a page number off-hand.

inherent: existing in someone or something as a permanent and inseparable element, quality, or attribute

The question now is whether the ability bonus is inherent to the base creature or to the PC.

If it's like a lot of things in 3.5 it'd probably stick and apply even after polymorphed, regardless of what the definition of inherent is even if the fluff meant "inherent to the base creature".
