[mueller at gcc dot gnu dot org]

the following testcase from KDE source can not be compiled with gcc 4.1 or
newer: 

=== Cut ===
int qHash(char key);
int qHash(int key);

template <class Key> struct QHash
{
   void findNode(const Key &key) { qHash(key); }
};

namespace khtml {

struct Font
{
    struct ScalKey
    {
    };
};

}

int qHash (const khtml::Font::ScalKey& key);


static QHash<khtml::Font::ScalKey>* scalCache;

void isFontScalable()
{
    khtml::Font::ScalKey key;

    scalCache->findNode(key);
}
=== Cut ===
