	* dwarf2read.c (dwarf2_start_subfile): Change prototype to accept
	compilation directory as last argument.
	Always pass comp_dir as second argument to start_subfile and prepend
	dirname to the filename when necessary.
	Remove now superfluous search for pre-existing subfile.
	(dwarf_decode_lines): Pass the compilation directory to
	dwarf2_start_subfile.
