In elf32.em, there's this code:

     FIXME: This approach--using bfd_elf_set_dt_needed_name--is not
     very pretty.  I haven't been able to think of anything that is
     pretty, though.  */
  if (bfd_check_format (entry->the_bfd, bfd_object)
      && (entry->the_bfd->flags & DYNAMIC) != 0)
    {
      char *filname, *needed_name;

      ASSERT (entry->is_archive && entry->search_dirs_flag);

      /* Rather than duplicating the logic above.  Just use the
	 filename we recorded earlier.o

	 First strip off everything before the last '/'.  */
      filename = strrchr (entry->filename, '/');

Shouldn't the variable be called 'filename'?

   In elf32.em, there's this code:

	FIXME: This approach--using bfd_elf_set_dt_needed_name--is not
	very pretty.  I haven't been able to think of anything that is
	pretty, though.  */
     if (bfd_check_format (entry->the_bfd, bfd_object)
	 && (entry->the_bfd->flags & DYNAMIC) != 0)
       {
	 char *filname, *needed_name;

	 ASSERT (entry->is_archive && entry->search_dirs_flag);

	 /* Rather than duplicating the logic above.  Just use the
	    filename we recorded earlier.o

	    First strip off everything before the last '/'.  */
	 filename = strrchr (entry->filename, '/');

   Shouldn't the variable be called 'filename'?

Actually, I think the uses of it should be filname, to avoid
shadowing.  Or we should just remove the declaration of filname, and
use the existing filename local.

Jeff, I'm not sure it's a good idea to try for the .sl extension on
every system type, given that it is only meaningful on HP/UX.  If
there is a long search path, it is a waste of time.  It is also
incorrect in principle.  You can test for a particular emulation using
#ifdef TARGET_IS_xxx.

I didn't know we could use TARGET_IS_xxx to do this stuff.  I'll certainly
change it.  I'm no fan of the current behavior applying to all targets.

Thanks for pointing it out.

I found out what happened with this.

Uli never checked in the version that conditionalized the hpux check to
the binutils repository.  Ugh.

Instead of using a TARGET_IS_xxx, he has a macro which specifies an alternate
shared library extension to check.  That seems to make more sense to me as
other targets could potentially use it if necessary.

One last thing.  Yes, the "filname" variable should just disappear.  I'll
take care of that too.

I'm testing the changes now..
