* targets.c (proto write_armap). Changed orl_count to unsigned.
* opncls.c (bfd_close_all_done). Added so that generative programs like gas can close a bfd without causing bfd confusion. * libbfd.h (changed becuase of protos) * amdcoff.c: messed with the way that jmp displacements are calcualated. This may not yet be totally correct. * archive.c (coff_write_armap): rewrote the way that ranlibs are written out. * coffcode.h (fixup_symbol_value): now doesn't core dump if a non abs symbol has no section (like a register symbol). (coff_write_symbol) now zeros auxent before filling it up to help with sensitive applications. * libbfd.c (bfd_write_bigendian_4byte_int): added.
