* coff-i386.c (coff_i386_reloc): Handle R_IMAGEBASE.
	(RTYPE2HOWTO): Return NULL if reloc type is out of range.
	(coff_i386_rtype_to_howto): Likewise.
	* coffcode.h (coff_slurp_symbol_table): Change a -2 to N_DEBUG.
	Completely ignore symbols which are all zero.
	(dummy_reloc16_estimate): Add return 0.
	* cofflink.c (_bfd_coff_link_input_bfd): Rename inner scope
	variable copy to name_copy to avoid shadowing outer scope
	variable.
	* libcoff-in.h (coff_data_type): Change raw_syment_count field
	from unsigned int to unsigned long.  Add timestamp field.
	* libcoff.h: Rebuild.
