That code should have failed immediately!  If it ever got to a code
review, it should have been shot dead immediately.  You  NEVER
assume that there's something beyond where you put it, unless ...
you put it there.	;-)

#define NUL	'\0'	/* Now, class, tell me why this is not NULL. */

	char buffer[BUFLEN+1];
		...
	fread(buffer, 1, BUFLEN, infile);
	buffer[BUFLEN] = NUL;
	len = strlen(buffer);	/* if you must */
