[Bug c++/16301] New: ICE with strong using

[bangerth at dealii dot org]

Not important, but maybe worth fixing sometime anyway: 
------------------ 
namespace NS2 
{ 
  using namespace NS1 __attribute__ ((strong)); 
} 
------------------ 
 
g/x> /home/bangerth/bin/gcc-3.4-pre/bin/c++ -c y.cc 
y.cc:3: error: expected namespace-name before "__attribute__" 
y.cc:3: error: `<type error>' is not a namespace 
y.cc:3: internal compiler error: tree check: expected namespace_decl, have 
error_mark in parse_using_directive, at cp/name-lookup.c:3409 
Please submit a full bug report, 
with preprocessed source if appropriate.
