Log message:
	2005-09-23  Paul Thomas  <pault@gcc.gnu.org>
	
	PR fortran/16861
	* module.c (mio_component_ref): Return if the symbol is NULL
	and wait for another iteration during module reads.
	(mio_symtree_ref): Suppress the writing of contained symbols,
	when a symbol is available in the main namespace.
	(read_module): Restrict scope of special treatment of contained
	symbols to variables only and suppress redundant call to
	find_true_name.
