I have a hard time taking the above && seriously.  pwd is a shell
builtin (when we are not talking about Version 3 UNIX or something) that
can hardly fail.  And when your shell does not support assignment to a
shell variable, you'll have a hard time getting the shell script to run.

That's stuff of the

    if (1+1 != 2) { fputs("Warning: your CPU may be broken", stderr); }

variety.  If you have to check for that, you have bigger problems...
