This header breaks my code, I have ev.pyx that includes ev.h,
actually I can change that to <ev.h> but I don't like it this way too..

And it actually produces bad code for me:

/* "ev.pxd":3
 * cimport libev
 *
 * cdef api enum:             # <<<<<<<<<<<<<<
 *     EV_NONE  = libev.EV_NONE
 *     EV_READ  = libev.EV_READ
 */
enum  {

  /* "ev.pxd":6
 *     EV_NONE  = libev.EV_NONE
 *     EV_READ  = libev.EV_READ
 *     EV_WRITE = libev.EV_WRITE             # <<<<<<<<<<<<<<
 *
 * cdef:
 */
  EV_NONE = EV_NONE,
  EV_READ = EV_READ,
  EV_WRITE = EV_WRITE
};

Yes, that would be nice.
