Assignment in test: OK?

[Jeffrey T. Hutzelman]

John,
    Good idea; it works great as long as you aren't trying to compare 2
variables.  However, I think the intent of the original code was to
perform an assignment and then do a test on the result (look carefully;
there's a > or < in there somewhere), similar to the following, which I
use all the time:

if ( ( file_ptr = fopen (filename, mode) ) == NULL )
	{
	/* print a message and exit */
	}
