Yet another blender link failure:

`btAxisSweep3Internal<unsigned int>::~btAxisSweep3Internal()':
/home/edwin/clangtests/blender-2.49b/source/gameengine/Converter/BL_BlenderDataConversion.cpp:(.gnu.linkonce.t._ZN20btAxisSweep3InternalIjED0Ev+0x27):

Here is a testcase:
class btVector3
{
};
class btOverlappingPairCache;
class btBroadphaseInterface
{
};
template < typename BP_FP_INT_TYPE > class btAxisSweep3Internal:public
  btBroadphaseInterface
{
protected:BP_FP_INT_TYPE m_bpHandleMask;
  inline void operator  delete (void *ptr)
  {
  }
public:btAxisSweep3Internal (const btVector3 & worldAabbMin,
            const btVector3 & worldAabbMax,
            BP_FP_INT_TYPE handleMask,
            BP_FP_INT_TYPE handleSentinel,
            BP_FP_INT_TYPE maxHandles =
            16384, btOverlappingPairCache * pairCache =
            0, bool disableRaycastAccelerator = false);
  virtual ~ btAxisSweep3Internal ();
};

class bt32BitAxisSweep3:public btAxisSweep3Internal < unsigned int >
{
public:bt32BitAxisSweep3 (const btVector3 & worldAabbMin,
             const btVector3 & worldAabbMax, unsigned int maxHandles =
             1500000, btOverlappingPairCache * pairCache =
             0, bool disableRaycastAccelerator = false);
};
bt32BitAxisSweep3::bt32BitAxisSweep3 (const btVector3 & worldAabbMin,
                      const btVector3 & worldAabbMax,
                      unsigned int maxHandles,
                      btOverlappingPairCache * pairCache,
                      bool disableRaycastAccelerator):
     btAxisSweep3Internal < unsigned int >(worldAabbMin, worldAabbMax,
                       0xfffffffe, 0x7fffffff, maxHandles,
                       pairCache,
                       disableRaycastAccelerator)
{
}

And here is the test script (_ZN20btAxisSweep3InternalIjEdlEP is the missing
symbol):

#!/bin/bash
/home/edwin/llvm-git/obj/Release/bin/clang++ x2.i -c -o x.o 2>/dev/null || exit
1
nm x.o | grep _ZN20btAxisSweep3InternalIjEdlEPv |grep " U " || exit 1
g++ x2.i -c -o x.o 2>/dev/null || exit 1
nm x.o | grep _ZN20btAxisSweep3InternalIjEdlEPv |grep " U " && exit 1
exit 0
