         * syntax.h: Adjust decls to match defn changes elsewhere.
         (struct gl_state_s):
         Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
+        (SETUP_SYNTAX_TABLE_FOR_OBJECT): Use PTRDIFF_MAX, not
+        MOST_POSITIVE_FIXNUM.
         * sysdep.c (wait_for_termination_1, wait_for_termination)
         (interruptible_wait_for_termination, mkdir):
         Don't assume pid_t fits in int; on 64-bit AIX pid_t is 64-bit.
