* trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
bfd_zalloc for rawptr, because later on we may call free, not bfd_release, on it. * bfd.c (struct _bfd): Add cisco_core_struct to tdata union. * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors. * cisco-core.c: New file. * Makfile.in: Change accordingly. * bfd-in2.h: Rebuilt.
