+ (som_prep_headers): Allocate space for and attach a file header
+ to the output bfd. For executables, use the saved system_id
+ value rather than trying to guess the right value. Do not abort
+ wwhen setting file_hdr->entry* for executables.
+ (som_begin_writing): For executables, set the exec_entry and
+ exec_flags fields.
+ (som_copy_private_backend_section_data): Always return a value.
+
+ * libhppa.h (PA_PAGESIZE): Define.
+
+ * som.c (SOM_ALIGN): Define.
+ (som_begin_writing): If writing an executable, initialize all
+ fields in the exec header to zero. Update fields in the exec
+ header as sizes of loadable subspaces are computed. Carefully
+ preserve alignments when building executables. Actually write the
+ exec after all the fields are filled in.
+
+ * Better long-filename handling. Reads SOM ABI compliant extended
+ names, but doesn't quite write compliant extended names yet.
+ * som.c (som_slurp_extended_name_table): Delete function. The
+ generic code will handle things correctly.
+ (som_slurp_armap): Seek to the beginning of the next member.
+ (normalize): New function.
+ (som_bfd_ar_write_symbol_stuff): Take the size of the extended
+ name table into account when computing the file offsets in the
+ SOM dictionary. Make sure to align to an even boundary.
+ (som_write_armap): Initialize the checksum to zero.
+ (ar_maxchars): Fix. Opps.

+ * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
+ machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.

+ * bfd-in.h (BFD_VERSION): Use @VERSION@.
+ * Makefile.in (bfd.h): Replace it with contents of VERSION file.
+ * bfd-in2.h: Regenerated.
+
+ * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
+ this was also named trad_unix_bfd_copy_private_bfd_data.

+ * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
+ elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
+ returns NULL, it is not an error. It's possible that some of
+ these checks are not necessary (because the size can never be
+ zero), but putting in the checks is the conservative thing to do
+ in light of the fact that some of these malloc calls replaced
+ unchecked alloca calls, in which a zero argument would work fine.

+ * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
+ duplicate definition.
+ (osf_core_bfd_is_local_label): Define.
+
* reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
failure indication, it merely means there are no relocs.
