* It seems that when using GNU/EDMA within an SDL application, obj_cast functions
  produce a segmentation fault.

  A new identical function was added (edma_newcast_obj) and this way it works ???

* If anchor points matches class names, inheritance cycles can appear which
	can crash the application.
		
	USE SOME RULE TO ENSURE anchor points NEVER MATCH class name
	For example prepend underscore on anchor_points
