This may be a problem in case when 'printed' is previously allocated to some
size that is less than the one that is given by the current 'cl_options_count'.
So perhaps this should rather be something like:
printed = xrealloc (printed, cl_options_count);
memset (printed, 0, cl_options_count);
That is if there is anything like 'xrealloc' (I didn't check), but you get the
idea. This should be safe, right?
(And BTW, I allways use "make bootstrap" with 3-stage compilation and the
result is the same, so that isn't the issue.)
