Generally I write my fwrite calls to write n elements of 1 byte in
length, so that it will return the number of bytes written. This is
indeed a problem if you ever need to write more than 4 GB of data in
one transaction, and size_t has a 32 bit definition. I can't think of
any use case, particularly with curl, where this would be necessary,
