Description:
Fails to compile on 64-bit architectures. For example, on ia64,

http://buildd.debian.org/fetch.php?&pkg=mysql-query-browser&ver=1.1.12-1&arch=ia64&stamp=1...

MGResultSetModel.cc: In member function `virtual bool 
   MGResultSetModel::iter_nth_child_vfunc(GtkTreeIter*, const GtkTreeIter*, 
   int)':
MGResultSetModel.cc:156: warning: cast to pointer from integer of different 
   size
MGResultSetModel.cc: In member function `virtual bool 
   MGResultSetModel::get_iter_vfunc(GtkTreeIter*, const Gtk::TreePath&)':
MGResultSetModel.cc:220: warning: cast to pointer from integer of different 
   size
MGResultSetModel.cc: In member function `virtual void 
   MGResultSetModel::get_value_vfunc(const Gtk::TreeIter&, int, GValue*)':

   MGResultSetModel::get_value(const Gtk::TreeIter&, int&, void*&, gsize&)'
MGResultSetModel.cc:227: error: candidates are: bool 
   MGResultSetModel::get_value(const Gtk::TreeIter&, unsigned int, void*&, 
   guint&)
MGResultSetModel.cc: In member function `Gtk::TreeIter 
   MGResultSetModel::append()':

Suggested fix:
See attached patch.

But, I do have some concerns about casting int <-> pointers since on 64-bit architectures sizeof(int) != sizeof(void*) since sizeof(long)==sizeof(void*). Are these casts valid? If these casts are actual pointers, then mysql-query-browser will NOT work on 64-bit architectures, including Amd64.

I was able to reproduce this using WinXP64 & AMD64

1.1.14 has even more of these problems.

Is there any movement on this? I cannot get any of these versions to work: 1.1.17, 1.1.14, 1.1.12. They all die at the pointer cast. Is this at all related to http://bugs.mysql.com/bug.php?id=8340 ?

For 1.1.17 you need to edit:
MGResultSetModel.cc file:
402:       if (get_value(iter_, (unsigned int)column, data, (guint&) size))
MQResultSetView.cc
1885:    if (_model->get_value(iter, (unsigned int) column*2, fdata, (guint&) fsize))
similar changes to lines 1911 and  1985
