I might have a guess. See below.

What causes this compiler error is this line:

    expected_size = statbuf.st_size;

Where 'expected_size' is declared a ssize_t.

I think this is because your operating system header's have the 'st_size'
field of the 'struct stat' of a type that isn't possible to assign to a
"signed integer" which ssize_t is.

The solution?

Well, libcurl currently has no proper support for large files, so I think it
would be an idea (as a short-term fix) to make expected_size a double and
then typecast the assignment. Like in this patch:

I'd be happy to get to know if this works.

I'm also interested in getting the large files support fixed once and for
all, should anyone want to grab that issue.
