+Mon May 13 10:03:29 1991  Steve Chamberlain  (steve at cygint.cygnus.com)
+
+       * aout.c: fixxed some of the problems with filepos calculation.
+       (swap_ext_reloc): fixed problem with creation of relocs.
+
+       * coff-code.h: (swap_filehdr_in, swap_filehdr_out) add.
+       (swap_filehdr) delete. Changed all the usage of bfd_h_put_x.
+       (swap_aouthdr_in, swap_aouthdr_out) add. (swap_aouthdr) delete.
+       (coff_real_object_p) cleaned up, added MIPS. (coff_object_p)
+       cleaned up. (coff_write_object_contents) cleaned up.
+
+       * ecoff.c: Totally different. Now supports ecoff fully.
+
+       * icoff.c: fixed problems in relocation callout.
+
+       * libcoff.h: (struct icofdata) removed hdr structure from tdata.
+
+       * m68kcoff.c: updated target vector.
+
+       * sunos.c: (choose_reloc_size) added: (sunos4_callback) calls
+       choose_reloc_size. (sunos4_write_object_contents) now calls
+       choose_reloc_size so outputs relocs correctly.
