* coffcode.h (coff_compute_section_file_positions): Keep the raw size safe. (coff_write_object_contents): Remember if it's a relocatable file. * libcoff-in.h (pe_data_type): New member 'has_reloc_section' * peicode.h (coff_swap_filehdr_out): Clear not-reloc flag if relocatable file. Swap out saved raw size.
