Nobody uses these functions anymore, so it doesn't seem particularly useful to implement them now, given that snprintf() provides almost equivalent functionality. Any active standards that still require them will most likely drop them in the near future. Is there a particular application you were trying to compile that prompted you to submit these patches?
