"bodypart" parameter does exist in the file you linked above so it was the updated version of it to fix those two errors. If you are sure that a_samp.inc is updated to 0.3.7 and the forwards are like this:

pawn Код:

forward OnPlayerTakeDamage(playerid, issuerid, Float:amount, weaponid, bodypart);
forward OnPlayerGiveDamage(playerid, damagedid, Float:amount, weaponid, bodypart);

you better look at other includes that use those two callbacks.

Though, you should consider to YSI 4.0 as Crayder already suggested.
