[c++] Missing strstream.h

[Tapio Kelloniemi]

Hi

GCC (3.3.3) currently seems to miss strstream.h from the
backward-compatibility include-directory. Only strstream is present,
which old legacy code of course does not use. I think it should be
added to make old code work without changes on g++ 3.3, and it is not
even a big thing.

I'm sorry, but I'm not subscribed to this list, the load of messages
is too voluminous so I can only read replies also sent to my address.
