It depends on a few things, such as when in the previous level they get polymorphed and the DM's rules on levelling up. None of which is clearly defined in the DMG as has already been stated several times. There's a reasonable likelihood that the 'someone' becomes an NPC and the question becomes moot.
What if he was Polymorphed permanently via Baleful Polymorph (which does have those rules) into a cat, and he kept his personality. Can he take Multiattack with his Claw/Claw/Bite routine? INA: Claw?
Sure. Now, tell me why this question is pertinent.
You stated that it doesn't make sense for the Fighter to be able to gain a feat if he only met the prerequisites for only a few minutes just before he levels up. But what if that is exactly what happens? What if he's had 10 Strength from permanent drain for the entire level and only minutes before levelling up had it restored? Doesn't that violate your paradigm? What if he was from a race that has natural claw attacks, but he was tortured and had his claws chopped off, leaving with no natural claw attacks, but then he received a Regenerate spell minutes before levelling up?
