My current local copy definitions block for these compiler/system looks like:

#elif defined(__POCC__)
  #if (__POCC__ < 280)
    typedef long curl_off_t;
    #define CURL_FORMAT_OFF_T "%ld"
    #define CURL_SIZEOF_CURL_OFF_T 4
  #elif defined(_MSC_VER)
    typedef signed __int64 curl_off_t;
    #define CURL_FORMAT_OFF_T "%I64d"
    #define CURL_SIZEOF_CURL_OFF_T 8
  #else
    typedef long long curl_off_t;
    #define CURL_FORMAT_OFF_T "%lld"
    #define CURL_SIZEOF_CURL_OFF_T 8
  #endif

#elif defined(__LCC__)
  typedef long curl_off_t;
  #define CURL_FORMAT_OFF_T "%ld"
  #define CURL_SIZEOF_CURL_OFF_T 4
