Commit f8117f55 ("http: use off_t to store partial file size", 02-11-2015) changed the type of some variables from long to off_t. Unfortunately, the off_t type is not portable and can be represented by several different actual types (even multiple types on the same platform). This makes it difficult to print an off_t variable in a platform independent way. As a result, this commit causes gcc to issue some printf format warnings on a couple of different platforms.
In order to suppress the warnings, change the format specifier to use the PRIuMAX macro and cast the off_t argument to uintmax_t. (See also the http_opt_request_remainder() function, which uses the same solution).
