At least here your #ifdef isn't inside (), but it is inside a function
body.  Have I mentioned that I like my #ifdefs hoisted to the top level,
when possible? :)

Here, you could avoid the #ifdef, and just write:

/* cast away any const */
libxl_event_free(priv->ctx, (libxl_event *)event);

At any rate, ACK to your series, whether or not you clean up the #ifdefs.

Thanks Eric.  I made your suggested changes and pushed the patches.
