AFAICS this boils down to whether djgpp/OW can support >2GB files
or not. Since neither of them have a 64-bit fseek() function they cannot
handle huge files. True or false? If so, curl_off_t should be a 'unsigned int'
(which maps to 16 or 32-bit depending on model (small/large/flat))).

64-bit in large model? I don't think that works. I think you

#if defined(__WATCOMC__) && defined(__386__)
    typedef signed __int64 curl_off_t;
