	* dbxread.c (process_one_symbol): When finding an N_FUN symbol
	that marks the end of the range of a function, enter a line number
	entry that has a line number of zero and a PC offset that matches
	the end of the function.  This starts a range of PC's for which no
	line number information is known.
	* symtab.c (find_pc_sect_line): If our best fit is in a range of
	PC's for which no line number info is found (line number is zero)
	then we didn't find any valid line information.
	* symtab.h: Document use of zero line number entry.
