[libgfortran/patch] Support NAMELIST I/O of derived type variables (library side)

[Victor Leikehman]

2004-08-15  Victor Leikehman  <lei@il.ibm.com>

	* io/transfer.c (st_set_nml_var), io/write.c (namelist_write): Take into
	account the possibility that st_set_nml_var is called with nulls in
	var_name and var_name_len.  This happens when passing anonymous fields
	of derived type variables. For strings, use string_length field instead
	of len. io/io.h (struct namelist_type): New field string_length.
	(st_set_nml_var_char): New argument string_length.
