I get uninitialised variable usage errors when I try to build it, in this
section of elf_link_is_defined_archive_symbol():

>   if (elf_bad_symtab (abfd))
>     {
>       extsymcount = symcount;
>       extsymoff = 0;
>     }
>   else
>     {
>       extsymcount = symcount - hdr->sh_info;
>       extsymoff = hdr->sh_info;
>     }

Looks like symcount and hdr aren't initialized if extsymcount was nonzero in
the previous conditional?
