	* resrc.c (write_rc_rcdata): Fix local variable shadowing
	problem.  If RCDATA_BUFFER data can be read as strings, modify
	code to print the strings as comments.
	* resres.c: Add casts to avoid warnings.
	(write_res_data, read_res_data): Don't put the program name in the
	error message; fatal already puts it there.
