Glue in some dowel in the oversized holes when it has set drill out

hinge so the screws are going into fresh wood. If the hinges are in
recesses then these will have to be redone and the old recesses
filled, but being an out building you may not be that fussy. Try a
rain deflector on the bottom edge of the door a see if that helps.

The dowel trick is easy and gives a result as good as the original wood IME.
