gcc 4.1 c++ build problem kdegames4

[Mark Davies <mark%ecs.vuw.ac.nz@localhost>]

Trying to build kdegames4 4.6.2 but its tripping up on a GCC 4.1 
issue:

/local/src/work/pkgsrc/games/kdegames4/work.i386/kdegames-4.6.2/libkdegames/kgamerenderer.h:
211: error: expected ',' or '...' before '>' token
/local/src/work/pkgsrc/games/kdegames4/work.i386/kdegames-4.6.2/libkdegames/kgamerenderer.h:
211: error: wrong number of template arguments (1, should be 2)
/local/src/work/pkgsrc/games/kdegames4/work.i386/.buildlink/qt4/include/QtCore/qdatastream.h
:66: error: provided for 'template<class Key, class T> class QHash'
/local/src/work/pkgsrc/games/kdegames4/work.i386/kdegames-4.6.2/libkdegames/kgamerenderer.h:
211: error: default argument missing for parameter 5 of 'QPixmap 
KGameRenderer::spritePixmap
(const QString&, const QSize&, int, const QHash<QColor, QColor>&, 
QColor) const'


the relevant line of kgamerenderer.h reads

          QPixmap spritePixmap(const QString& key, const QSize& 
size, int frame = -1, 
const QHash<QColor, QColor>& customColors = QHash<QColor, 
QColor>()) const;


Apparently this builds fine with GCC4.4 but that doesn't help us 
and there is an open kde bugreport about it (261488) but that has 
no help.

Anyone have suggestions on how to work around this and get it to 
build with 4.1?

cheers
