Anton, I'm afraid the original developer of this is no longer around and 
  if there is no other response, the best thing would be to check the 
behaviour in the source as I don't think these special %rename features 
are widely understood or used.

For issue 2 you can workaround the casing problem by using either 
%csconst(0) or %csconstvalue with %csconst(1) (for c#).
