[Bug c++/36709] New: Compiler allows namespace and class to have same name and doesn't generate ambiguous reference error when it should result from this.

[rquabili at princeton dot edu]

Since J is already defined, the namespace declaration should generate an error
("int J; namespace J{}" does generate an error). G++ gets confused with the g()
call and instead of generating an error it passes the problem to the assembler.

main.cpp:
struct J {
    static void g() {}
};
namespace J {
    void g() {}
}
int main() {
    J::g();
    return 0;
}

Using built-in specs.
