examples: Work around mingw printf() weakness

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.
