I have a better idea that does not require an extra include file:

  #define TASK_STATUS_ENUM(VALUE) ts##VALUE
  #define TASK_STATUS_ENUM_COMA(VALUE) TASK_STATUS_ENUM(VALUE) ,

  #define TASK_STATUS_VALUES(_) _(Normal) _(ModifiedLocally) _(CreatedLocally)

  enum TaskStatus { TASK_STATUS_VALUES(TASK_STATUS_ENUM_COMA) };

  #define STRINGIFY_VALUE(v) "ts" #v
  #define ENUM_TO_STR(x) if (status == TASK_STATUS_ENUM(x)) return STRINGIFY_VALUE(x);

  char* enumToStr(TaskStatus status) {
    TASK_STATUS_VALUES(ENUM_TO_STR);
    return STRINGIFY_VALUE(Normal);
  }

We have these in our main product at work. They are powerful and very useful but they can get out of hand and be difficult to debug or add code to.
