[Pyrex] typedef enum

[Tom Kobialka]

Hi,

  I'd like to transalte the following into pyrex code, I'm a bit lost as 
to how to approach it, perhaps an array ?

typedef  enum
	      {FRNATIVE,
                FRSWAP,
                FRCONTRACT,
                FREXPAND,
                FRCONTRACT_AND_SWAP,
                FREXPAND_AND_SWAP} FRFORMAT;



  I don't think I can translate the following into pyrex, is there some 
way I can circumvent the #ifdef issue?

	typedef struct FrIO{
		#ifdef FRIOCFILE
   		  FILE *fp;
		#else
   		  int fd;
		#endif
   		 char buffer[FRIOBSIZE];
   		 int  position ;

	};

  Thanks in advance.

Tom
