I must say you are comming a bit strong here, don't you think? The fact that 
you were using unsupported configuration which doesn't work anymore is IMO 
minor inconvinience.

All you need in this file is

#define BOOST_TEST_MAIN
#include <boost/test/unit_test.hpp>

This file may look like this:

 #include "../Jacobi.h"
 #include <boost/test/unit_test.hpp>
 #include <stdexcept>

BOOST_AUTO_TEST_SUITE( Jacobi_iteration_test_suite )

BOOST_AUTO_TEST_CASE( JacobiTest1 )
{
   DenseMatrix A(2, 3);
   Vektor x(3, 1.0);
   Vektor y(2, 1.0);
   Jacobi jacobi;
   BOOST_CHECK_THROW(jacobi.solve(A, x, y), std::logic_error);
}

BOOST_AUTO_TEST_SUITE_END()

This file may look like this:

#include "../GaussSeidel.h"

 #include <boost/test/unit_test.hpp>
#include <boost/test/floating_point_comparison.hpp>

BOOST_AUTO_TEST_SUITE( Gau?_Seidel_iteration_test_suite )

BOOST_AUTO_TEST_CASE( GaussSeidelTest4 )
{
  DenseMatrix A(3, 3);
  Vektor x(3);
  Vektor y(3);
  GaussSeidel gs1("damped Gau?-Seidel (SOR)", 0.5, 1); // 1 iteration
  gs1.solve(A, x ,y);
  BOOST_CHECK_CLOSE(X[0], -108.0/240, 1E-10);
  BOOST_CHECK_CLOSE(X[1], -27.0/240, 1E-10);
  BOOST_CHECK_CLOSE(X[2], 38.0/240, 1E-10);
}

BOOST_AUTO_TEST_SUITE_END()

Don't you think this look a bit neater? And it works both with static and 
shared library. All you need is to define BOOST_TEST_DYN_LINK in makefile 
during compilation to be able to link with shared library. And this works 
for both *nix and NT.
