+
+ * targets.c (proto write_armap). Changed orl_count to unsigned.
+ * opncls.c (bfd_close_all_done). Added so that generative
+ programs like gas can close a bfd without causing bfd confusion.
+ * libbfd.h (changed becuase of protos)
+ * amdcoff.c: messed with the way that jmp displacements are
+ calcualated. This may not yet be totally correct.
+ * archive.c (coff_write_armap): rewrote the way that ranlibs are
+ written out.
+ * coffcode.h (fixup_symbol_value): now doesn't core dump if a non
+ abs symbol has no section (like a register symbol).
+ (coff_write_symbol) now zeros auxent before filling it up to help
+ with sensitive applications.
+ * libbfd.c (bfd_write_bigendian_4byte_int): added.
+
+Wed Oct 16 22:58:45 1991 John Gilmore (gnu at cygnus.com)
+
+ * bfd.c: Make sure we don't get a macro strerror().
+ * opncls.c (bfd_fdopenr): If FASCIST_FDOPEN, use "r", not "r+".
+ * trad-core.c (trad_unix_core_file_failing_command): Suppress
+ attempt to recover command, ifdef NO_CORE_COMMAND.
+ * hosts/h-tahoe.h: Add FASCIST_FDOPEN and NO_CORE_COMMAND;
+ revamp HOST_*, etc.
+ * hosts/h-i386v.h: Use <utime.h>, not <sys/utime.h>, unlike POSIX.

* archive.c (bsd_write_argmap): The size of the ranlib structures
- should not include teh size field itself.

* aoutx.h, libaout.h (NAME(aout, sizeof_headers)): Use
adata(abfd)->exec_bytes_size field instead of constant macro,
because aoutx.h compiles to a simple .o file shared by
An archive is represented internally just like another BFD, with a
pointer to a chain of contained BFDs. Archives can be created by
-opening BFDs, linking them together and attatching them as children to
+opening BFDs, linking them together and attaching them as children to
another BFD and then closing the parent BFD.
