+ * config.bfd configure.host: Match on *-lynxos* for LynxOS,
+ add m68*-*-lynxos*.
+ * configure.in : Replaced i386lynx_vec with i386lynx_aout_vec
+ and i386lynx_coff_vec.
+ Added m68klynx_aout_vec and m68klynx_coff_vec.
+ * targets.c (target_vector): Removed i386lynx_vec, added
+ {i386,m68k}lynx_{aout,coff}_vec.
+ * i386lynx.c: Added copy of i386coff.c, renamed bfd target to
+ i386lynx_coff_vec.
+ * m68klynx.c: New file.
+ * config/i386-lynx.mt: Replaced i386lynx_vec with i386lynx_aout_vec
+ and i386lynx_coff_vec.
+ * config/m68k-lynx.mt: New file.
+ * config/i386lynx.h: Added definition of cfree as free (from Eichin).
+ * hosts/m68klynx.h: New file.
