>Description:
The following code fragment

// ...begin pig.cpp ...
typedef int T;
namespace A { typedef int T; }
using A::T;
// ... end pig.cpp ...

compiled with "gcc -c pig.cpp" gives the following error message.

pig.cpp:3: using directive `T' introduced ambiguous type `T'

This is incorrect, since there are no using directives in scope.
The error message should read 'using declaration' instead.
