[Bug c++/15188] New: Ambiguity caused by 'using' is misreported

[ghost at cs dot msu dot su]

Compiling the following program:  
 
namespace X { 
    class A {}; 
} 
 
namespace Y { 
    class A {}; 
} 
 
using X::A; 
using namespace Y; 
 
 
int main() 
{ 
    A a; 
    return 0; 
} 
 
Produces: 
namespaces.cpp: In function `int main()': 
namespaces.cpp:16: error: `A' undeclared (first use this function) 
namespaces.cpp:16: error: (Each undeclared identifier is reported only once for 
each function it appears in.) 
 
This is clearly wrong, there are two 'A' visible at the error point. And of 
course, when I comment out one of the 'using', the program compiles. If I use 
to using directives "using namespace X; using namespace Y;" the error is still 
the same. 
 
Gcc version is: 
gcc version 3.4.0 (Debian)
