Also, try the following:

#include <stdio.h>

enum test_enum {
  enum_1	= 1,
  enum_2	= 2,
  enum_3	= 3,
  enum_4	= 4,
  };

typedef struct {
	int val_int;
	unsigned char *val_string;
} TEST_STRUCT;

void main(void)
{
  enum test_enum type;
  TEST_STRUCT uval,*uvalp;
  int val;
	
  type = enum_4
  uval.val_int = 1;
  uvalp = &uval;
  val = 1;
	
  type = (enum test_enum)(uval.val_int);
  printf("struct and cast: type is %d (this should be 1)\n", type);
  type = enum_4

  type = uval.val_int;
  printf("struct, no cast: type is %d (this should be 1)\n", type);
  type = enum_4;
	
  type = (enum test_enum)(uvalp->val_int);
  printf("struct and cast through pointer: type is %d (this should be 1)\n", 
	type);
  type = enum_4;

  type = uvalp->val_int;
  printf("struct, no cast, through pointer: type is %d (this should be 1)\n",
	 type);
  type = enum_4;
}


This won't work in 3.1b1 or 3.1 final.
