3 patches for libstdc++

[Fred Richardson <frichard at bbn dot com>]

Here are 3 patches which fix small bugs in libstdc++:

     libstdc++/stl/stl_hashtable.h         Bug in SGI dist!
     libstdc++/stl/stl_hash_set.h          Ditto!
     libstdc++/std/bastring.h              Terminate now resizes if
                                           neccesary.
