Try: 
   without warning

I recall that in CGI apps exwc might not terminate if it
outputs warnings. It tries to say "Press Enter" and waits
for the user to press Enter (which never happens).

I'm not sure if this affects you or not, but
on Windows, file input from standard input (file 0)
is always in text mode (\r\n is converted to \n), so there will be 
problems if you need binary input. Things work fine
on Linux/FreeBSD. There may be a way to deal with this, but
no one ever got around to doing it (e.g. adding some command
to switch Windows standard input to binary).
