This thread is getting quite theoretical ;-) That was my reason for
asking if someone has actually tested the above mentioned condition.

I'm not saying that it doesn't work. I was just asking if someone has
actually had the time to verify that it works when using a
postfieldsize greater than (size_t)-1 on a platform where
sizeof(curl_off_t) > sizeof(size_t).

Its not a matter of trying to fight against everyone else :-)

But since at several points internal buffers are used, I have the
feeling that we are (size_t) limited. I might be completely wrong and
overlooking or missing something. That was also the reason for asking
for hard facts, practical ones not theoretical ones.

I know that I'm not providing evidence that it doesn't work. But I'm
not claiming that it doesn't work. That's another reason for me
claiming that I wouldn't change that specific code.
