Did you try :
	output = (struct outfile **) malloc(sizeof(struct outfile) * 3);

This goes through lint here, althougth lint complains that
        sizeof(struct outfile) * 3
is long, and should be unsigned.

So 
	output = (struct outfile **) malloc((unsigned)
                    sizeof(struct outfile) * 3);
should clear everything up.
