__dso_handle problem at link time.

Hi all,

I try to use a cpp class to use fixed point math library. So far i was
able to get everything work.

Now When I call a membre function of the class, i got an

undefined reference to `__dso_handle'

i'm not an expert at the configuration of cpp under the arm7.

here the complete link command

thanx for your help.
