mingw lacks %lld and %zu support in printf(); we were getting it from gnulib. But since commit acf522e8 stopped linking examples against gnulib, we are getting a build failure due to -Wformat flagging these strings. Keep the examples standalone, and work around mingw by using manual casts to types we can portably print.
