I am using the same tools as you are (except older versions:
binutils-2.9.1, newlib-1.8.2) and running under Linux.

To resolve the C++ ctor/dtor problem, I ended up writing my own dynamic
memory management function.

__builtin_delete ==> void operator delete [] (void *);
__builtin_vec_delete ==> void operator delete (void *);
__builtin_new ==> void* operator new (size_t);
__builtin_vec_new ==> void* operator new[] (size_t);

and read '==>' as "will be resolved if you have the function".

Hope this helps.
