dwarf2out.c (CIE_LENGTH_LABEL, [...]): New macros. 

Wed Nov 19 12:03:04 1997  Philippe De Muyter  <phdm@macqel.be>

	* dwarf2out.c (CIE_LENGTH_LABEL, FDE_LENGTH_LABEL): New macros.
	(ASM_OUTPUT_DWARF_VALUE4): New macro.
	(ASM_OUTPUT_DEFINE_LABEL_DIFFERENCE_SYMBOL): Define if SET_ASM_OP is
	defined.
	(output_call_frame_info): Do not output forward label differences
	if ASM_OUTPUT_DEFINE_LABEL_DIFFERENCE_SYMBOL is defined.
	* m68k/mot3300.h (SET_ASM_OP): Define when not using gas.
