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

#elif defined(__SYMBIAN32__)
  #if defined(__GCC32__)
    typedef long long curl_off_t;
    #define CURL_FORMAT_OFF_T "%lld"
    #define CURL_SIZEOF_CURL_OFF_T 8
  #elif defined(__CW32__)
    #pragma longlong on
    typedef long long curl_off_t;
    #define CURL_FORMAT_OFF_T "%lld"
    #define CURL_SIZEOF_CURL_OFF_T 8
  #elif defined(__VC32__)
    typedef signed __int64 curl_off_t;
    #define CURL_FORMAT_OFF_T "%I64d"
    #define CURL_SIZEOF_CURL_OFF_T 8
  #endif

#elif defined(__VMS)
  #if defined(__ALPHA) || defined(__IA64)
    typedef long long curl_off_t;
    #define CURL_FORMAT_OFF_T "%lld"
    #define CURL_SIZEOF_CURL_OFF_T 8
  #else
    typedef long curl_off_t;
    #define CURL_FORMAT_OFF_T "%ld"
    #define CURL_SIZEOF_CURL_OFF_T 4
  #endif
