gcc 3.3.3 is quite old at this point.

The error message means that some shared library is calling __gcov_init,
which is a hidden symbol. The way to fix this is to make sure that you
pass the --coverage option when you link the shared library. At least,
that will do the right thing with current gcc; I don't know for sure
that it will work with gcc 3.3.3.
