Back to the problem I was having with "cout << hex << number;", I tracked
down the bug to iostream.cc, so presumably it was an inherited bug from
libg++. If it is, please advise and I'll forward this there (I don't have
the full libg++ sources handy for comparison).

This is the diff which corrects the problem. As you can see, ios::showbase
was always in effect.

      }
      int buf_len = strlen(buf);
