I have done some more checking and I might have been wrong about the
Ubuntu and Linux in general. It looks like the formatting strings are
incompatible between MSVC and *NIX. It appears that either %S (SUSv2)
or %ls (C99) is needed on *NIX. MSVC switches the meaning of %s for
wprintf() (http://linux.die.net/man/3/printf).
