Here's a cut-down testcase: 
---------------------------------------------- 
namespace NS1 { 
  namespace NS2 { 
  }; 
} 
namespace NS2 { 
  class X; 
} 
using namespace NS1; 
 
typedef NS2::X Y; 
-------------------------------- 
 
It fails like so with 3.3: 
tmp/g> ~/bin/gcc-3.3/bin/c++ -c x.cc 
x.cc:10: error: syntax error before `::' token 
 
I think it should pass. I'm at a machine where I don't have my compiler collection, so 
I can't say whether this is a regression or what.
