* bfd-in.h (bfd_link_subsystem): Turn enum into #defines. (bfd_link_pe_info_dval): New (bfd_link_stack_heap): Renamed and massaged into bfd_link_pe_info. * bfd-in2.h: rebuilt. * bfd.c (NT_subsystem, NT_stack_heap): Deleted. * coffcode.h (pe_value): New function. (fill_pe_header_info): New function. (coff_write_object_contents): Use new function. * cofflink.c (coff_final_link_info): Remove pe randomness. (dores_com): Update info in bfd_link_pe_info_dval. (process_embedded_commands): Use the bfd_link_pe_info_dval. (_bfd_coff_final_link): Remove PE stuff, initialize coff_data->link_info. * coffswap.h (coff_swap_[aout|filehdr]_out): Use indirect PE pointer. (coff_swap_scnhdr_out): Use real imagebase. * libcoff (coff_data_type.link_info): New field.
