It is rather trivial to construct a GList of hash table keys (or
values) using g_hash_table_foreach. Of course it's only useful on
a table whose contents change never or seldom because the list
has to be updated on each change. Anyway, here's what I use. I
was too lazy to make Append_key() the right type.

void append_key(void *k, void *v, GList **keys)
{
}

GList *get_hash_keys(GHashTable *hash)
{
        GList *keys = NULL;
        
        g_hash_table_foreach(hash, append_key, &keys);
        return keys;
}
