wip/fs-uae and PySide

[Rhialto <rhialto%falu.nl@localhost>]

I have committed wip/fs-uae: finally we again have an Amiga emulator
that actually works! (emulators/uae and emulators/e-uae don't actually
work...)

I've done the stable release, but there is a development version that
has different prerequisites. In fact it has been split in 2, the
emulator itself, and the GUI frontend. And with the prerequisites for
the frontent (PySide: Qt4 bindings for Python) I have an issue.

PySide comes in several parts, including a code generator. For some
reason it forgets at some point that a pointer is const and g++ doesn't
like it. However on other platforms (Linux...) there is seemingly no
such problem.

My build proceeds this far:

Looking at the code at that place, I see

            if (!PyErr_Occurred()) {
                // filename()
                PyThreadState* _save = PyEval_SaveThread(); // 
Py_BEGIN_ALLOW_THREADS
                char * cppResult = cppSelf->filename();
                PyEval_RestoreThread(_save); // Py_END_ALLOW_THREADS
                pyResult = 
Shiboken::Conversions::copyToPython(Shiboken::Conversions::PrimitiveTypeConverter<const
 char*>(), cppResult);
            }


where the compiler complains about the

    char * cppResult = cppSelf->filename();

in the middle.
As far as I can see, g++ (gcc version 4.5.3 (NetBSD nb2 20110806) ) is correct. 
The filename() method returns a const char *. That seems to match what?s in 
?./tests/libsample/simplefile.h

It seems incorrect code generation that this is assigned to a plain char *.

Does anyone have an idea why I'd see this, and others apparently succeed
here?

I have started a forum thread at
http://qt-project.org/forums/viewthread/34477/ but so far there are no
reactions.
