[PyQt] build error with pyqt 4.4

[Erick Tryzelaar]

It looks like a change in between this release and
4.4-snapshot-20080508_0 broke my build. Here's the error:

Looking at a diff, it looks like this was a recent addition:

-PyObject *PyCustomWidgets::getModuleAttr(char *module, char *attr)
+PyObject *PyCustomWidgets::getModuleAttr(const char *module, const char *attr)
 {
+#if PY_VERSION_HEX >= 0x020500
     PyObject *mod = PyImport_ImportModule(module);
+#else
+    PyObject *mod = PyImport_ImportModule(const_cast<char *>(module));
+#endif

     if (!mod)
     {
         PyErr_Print();
         return 0;
     }

+#if PY_VERSION_HEX >= 0x020500
     PyObject *obj = PyObject_GetAttrString(mod, attr);
+#else
+    PyObject *obj = PyObject_GetAttrString(mod, const_cast<char *>(attr));
+#endif
+
     Py_DECREF(mod);

     if (!obj)
     {
         PyErr_Print();


I'm building this on leopard that has python 2.5 installed, but I'm
building it against python 2.4, so I think something's getting
confused somewhere.
