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). *big SIGH* -- VZ -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
