Subject: [PATCH] Fix build on 32-bit systems
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Because -Werror is set, some printf statements caused build errors on
32-bit systems when printing uint64_t. This can be handled in a portable
way by using the macros from inttypes.h …

Fixes: #12
