* src/autohint/ahhint.c (ah_hinter_align_weak_points): Remove

unused variable `edges'.
(ah_hinter_load): Remove unused variables `old_width' and
`new_width'.
* src/cid/cidload.c (cid_decrypt): Use `U' for constant (again).
* src/psaux/psobjs.c (T1_Decrypt): Ditto.
* src/type1/t1parse.c (T1_Get_Private_Dict): Ditto.
