Redhat Linux 7.2 (Intel), verified on gcc-3.1 and gcc-3.0.4
>Description:
The code below compiles, but it should not. The compiler is allowing a class and namespace to have the same name, but it should not.

FWIW, Comeau's compiler rejects this code.

namespace Foo
{
}

class Foo
{
};

int main()
{
}
>How-To-Repeat:
Compile the code in the description.

Output an error.
