  28. * Determine which string to integral data type conversion function we use
  29. * to implement string conversion to our curl_off_t integral data type.
  30. *
  31. * Notice that curl_off_t might be 64 or 32 bit wide, and that it might use
  32. * an underlying data type which might be 'long', 'int64_t', 'long long' or
  33. * '__int64' and more remotely other data types.
  34. *
  35. * On systems where the size of curl_off_t is greater than the size of 'long'
  36. * the conversion function to use is strtoll() if it is available, otherwise,
  37. * we emulate its functionality with our own clone.
  38. *
  39. * On systems where the size of curl_off_t is smaller or equal than the size
  40. * of 'long' the conversion function to use is strtol().
