Yeah, but the original patch pointed out that commit 2ac93be70641
removed arm-aout and arm-coff from BFD.  Without arm-coff in BFD, it
seems to me that this line in arm-wince-tdep.c will never cause the
sniffer to run:

  gdbarch_register_osabi_sniffer (bfd_arch_arm, bfd_target_coff_flavour,
				  arm_wince_osabi_sniffer);

Then, since that's the only thing that can return GDB_OSABI_WINCE, I
think the rest of the file must also be unusable.

thanks,
Tom
