re PR fortran/35627 (namelist read error)

2008-03-19  Jerry DeLisle  <jvdelisle@gcc.gnu.org>

	PR libfortran/35627
	* io/list_read.c (free_line): Clear the line buffer enable flag and
	reset the index into line_buffer, aka item_count.
	(next_char): Cleanup whitespace.
	(read_logical): Use unget_char to assure that the first character of the
	bad logical is saved in case it is part of an object name. Remove the
	clearing of index and flag that is now in free_line.
	(read_real): Likewise.
