  Modified files:
    lib/libarchive       Makefile 
                         archive_read_support_format_iso9660.c 
                         archive_write_set_format_ustar.c 
  Log:
  Unbreak libarchive on arm.  Two parts of libarchive relied on a
  traditional shortcut of defining on-disk layouts using structures of
  character arrays. Unfortunately, as recently discussed on cvs-all@,
  this usage is not actually sanctioned by the standards and
  specifically fails on GCC/arm (unless your data structures happen to
  be "naturally aligned").
  
  The new code defines offsets/sizes for data fields and accesses
  them using explicit pointer arithmetic, instead of casting to
  a structure and accessing structure fields.  In particular,
  the new code is now clean with WARNS=6 on arm.
