[Dune] gcc 4.3 compatibility

[Oliver Sander]

Hi Martin!
I did not do exhaustive tests.  As I said, my own applications compile, 
though.
That's mainly UGGrid, OneDGrid, YaspGrid, some dune-istl and dune-disc.
I am not saying that dune is g++-4.3-clear.  Only that there are a lot less
problems than I was expecting.

Apparently gcc-4.3 is the default for Debian Lenny as of today.  The 
change has
not made it to the mirrors yet, though.
