Hi. I have a few test cases that this fails (not quiet bad, but may be better not 
to break)



enum
  {
   A,
   B,|
   C,
  };

gives 'nil', which would better return 'enum' as it is common to have enums without
names associated.

int a[] = {'h', 'e', 'l', 'l', 'o', '\0'|};

gives "[" which I believe, should actually return 'nil' when defined at file scope.

typedef struct
{
  int a;
  int b;|
} nice;

returns "nice". It may be better to return "struct nice" as in "struct nice {...};" definition.

Thanks
