Changes to let BFD return an error indication from
	get_symtab_upper_bound, bfd_canonicalize_symtab,
	bfd_get_reloc_upper_bound, and bfd_canonicalize_reloc.  They now
	return long instead of unsigned int, and use -1 to indicate an
	error.  Along the way, rename get_symtab_upper_bound to
	bfd_get_symtab_upper_bound.
	* bfd.c (bfd_get_reloc_upper_bound): Return long, and -1 on
	errors.
	(bfd_canonicalize_reloc): Likewise.
	* syms.c (bfd_get_symtab_upper_bound): Renamed from
	get_symtab_upper_bound.
	* targets.c (bfd_target): Renamed _get_symtab_upper_bound to
	_bfd_get_symtab_upper_bound, and changed it and
	_bfd_canonicalize_symtab and _get_reloc_upper_bound and
	_bfd_canonicalize_reloc to all return long.

250578363e * libbfd.c (bfd_read): Set bfd_error as appropriate for a short
read. (bfd_error_system_call or bfd_error_file_truncated).

        * som.c: Do not blindly set bfd_error_system_call after a
        failing bfd_read, bfd_write, or bfd_seek.  In a few places
        (like som_object_p) override the error status set by bfd_read.

1c6042ee10 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
after NAME, since SunOS /bin/cc can't handle it.

Jim Kingdon
80425e6c82 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
cruft (like the #pragma alloca for AIX).
	In addition to that problem, the C alloca calls xmalloc, which
	means checking for being out of memory can't work right.  The
	following changes remove all uses of alloca from BFD.
	* hosts/solaris2.h: Remove alloca cruft.
	* som.c: Replace alloca with a fixed size auto array.
	* aoutx.h, elfcode.h, nlmcode.h, bout.c, coff-alpha.c, ecoff.c,
	ecofflink.c, elf32-hppa.c, elf32-mips.c, linker.c, reloc.c, som.c:
	Replace alloca with malloc and appropriate error checking and
	freeing.
	* linker.c: Replace alloca with obstack_alloc.
	* libbfd.h: Rebuilt.

0, instead of dropping core.
