Comment below is from curlbuild.h:
NOTE 2:
For any given platform/compiler curl_off_t must be typedef'ed to a
64-bit wide signed integral data type. The width of this data type
must remain constant and independent of any possible large file
support settings.
As an exception to the above, curl_off_t shall be typedef'ed to a
32-bit wide signed integral data type if there is no 64-bit type.
Data type definition of curl_off_t.
