[Kde-bindings] Does smokeqt support the Q3 support classes?

This appears to be a compiler issue.  The system I'm on at work is
using a very old gcc, gcc version 3.3.5 20050117 (prerelease) (SUSE
Linux).  I checked out cvs head of smoke and kalyptus, and still got
the above mentioned errors.  I got it to build ok at home on gcc
4.3.2, but I couldn't include all the headers. The headers I had to
exclude are:
/opt/qt-4.5.2/include/Qt3Support/q3dns.h
/opt/qt-4.5.2/include/Qt3Support/q3filedialog.h
/opt/qt-4.5.2/include/Qt3Support/q3memarray.h
/opt/qt-4.5.2/include/Qt3Support/q3progressdialog.h

Even though it compiles, I get some interesting compiler warnings,
like this one:
/opt/qt-4.5.1/include/Qt3Support/q3textedit.h:494: warning: ‘virtual
void Q3TextEdit::drawContents(QPainter*)’ was hidden
/home/cburel/src/smoke/kdebindings/build/smoke/qt/x_4.cpp:13003:
warning:   by ‘virtual void x_Q3TextView::drawContents(QPainter*, int,
int, int, int)’
Maybe 50 or so different methods produce that warning.

q3memarray.h I assume we don't need bindings for anyway, but for the
record the line
"operator QVector<type>() const;"
was not successfully parsed by kalyptus.  It died at line 1657 of
kalyptusCxxToSmoke.pm.

q3filedialog.h yeilds:
/home/cburel/src/smoke/kdebindings/build/smoke/qt/x_2.cpp: In static
member function ‘static void x_Q3FilePreview::x_1(Smoke::StackItem*)’:
/home/cburel/src/smoke/kdebindings/build/smoke/qt/x_2.cpp:2830: error:
cannot allocate an object of abstract type ‘x_Q3FilePreview’
/home/cburel/src/smoke/kdebindings/build/smoke/qt/x_2.cpp:2821: note:
 because the following virtual functions are pure within
‘x_Q3FilePreview’:
/opt/qt-4.5.1/include/Qt3Support/q3filedialog.h:88: note:
virtual void Q3FilePreview::previewUrl(const Q3Url&)
/home/cburel/src/smoke/kdebindings/build/smoke/qt/x_2.cpp: In static
member function ‘static void x_Q3FilePreview::x_2(Smoke::StackItem*)’:

cannot allocate an object of abstract type ‘x_Q3FilePreview’
/home/cburel/src/smoke/kdebindings/build/smoke/qt/x_2.cpp:2821: note:
 since type ‘x_Q3FilePreview’ has pure virtual functions

q3progressdialog.h yeilds:

For q3dns.h, the smoke lib built ok, but then won't link.  I had
modified the CMakeLists.txt to get libsmokeqt to link to the
Qt3Support library, but it still errors out with some undefined
symbols.  Even though I can run nm on the libQt3Support.so and see the
symbols defined there:
