Enumerations

RPC/XDR enumerations have similar syntax as C enumerations.

enum-definition:
   "enum" enum-ident "{"
 		enum-value-list
   "}"

enum-value-list:
   enum-value
   enum-value "," enum-value-list

enum-value:
   enum-value-ident
   enum-value-ident "=" value 
Here is an example of an XDR enum and the C enum to which it gets compiled.
enum colortype {               enum colortype {
 	RED = 0,                       RED = 0,
 	GREEN = 1,       -->           GREEN = 1,
 	BLUE = 2                       BLUE = 2,
};                             };
                               typedef enum colortype colortype;
