changed. Use frame_pc_unwind instead of
DEPRECATED_SAVED_PC_AFTER_CALL.
(i386_linux_init_abi): Don't set deprecated_register_bytes.
* i386bsd-tdep.c (i386bsd_sigcontext_addr): Rewrite.
* i386-nto-tdep.c (i386nto_sigcontext_addr): Adapt for new frame
unwinder.
* i386-cygwin-tdep.c: Don't include "gdbcore.h", "frame.h" and
"dummy-frame.h".
(i386_cygwin_frame_chain_valid, i386_cygwin_frame_chain): Removed.
(_initialize_i386_cygwin_tdep): New prototype.

gdbarch_info. Include "osabi.h" in gdbarch.c. Check osabi
in gdbarch_list_lookup_by_info and in gdbarch_update_p.
* gdbarch.c: Regenerated.
* gdbarch.h: Regenerated.
* osabi.c (gdbarch_lookup_osabi): Return GDB_OSABI_UNINITIALIZED if
there's no BFD.
