That manual is quite old. I can confirm that "%I64d" works for printing
an 'unsigned __int64' type for 32-bit targets (as it's defined now in <curl/curl.h>).
For small and large models, I have no idea really. But I think building libcurl
for those models is pointless (far too much code and data to fit in a 16-bit

What I meant was that small/large has 16-bit ints. Since I was mistaken
about 'long int' being the same as an 'int', the statement was wrong.
I.e. fseek() uses a 32-bit offset in *any* memory-model on Watcom/djgpp.
