Fixes warnings as per bug description
This is the well-known %lu with uint64_t again. It does actually result in bad
output: little-endian systems will show value mod 4G and big-endian will show
value / 4G.
The source already addresses this in 2 ways:
1. use %llu and cast to long long unsigned int
2. Use macro PRIu64 from <inttypes.h>
I offer a patch using method 2: using the macro still gets a warning if the
base type is inappropriate but with a cast there can be no warning</pre>
