  Or, you could just use the easiest solution, which is to tell /bin/sh
to use /bin/csh when parsing the command:

    system("/bin/csh -fc 'command_which_generates_errors >& /dev/null'");

(Yes, I know that if the /bin/csh which is executed prints out an error,
then it will be printed in the calling process.  I don't consider that
such a bad thing, given that if the shell has to print out an error then
there is something very wrong....)
