* 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.
