[boost] boost.test link error

Hi, 

My problem might be a beginner one, but I spent all day searching forums 
and mailing archives and it didn't help much, so I am asking at the 
source. 
The reason why I write this email is that modifying boost source helps but 
what I did is not enough. 

what I did : 
- a first test file using helper macros to test a class (works fine alone) 
: 
#define BOOST_TEST_MAIN 
#include <boost/test/unit_test.hpp> 
BOOST_AUTO_TEST_SUITE(Class1TestsSuite); 
BOOST_AUTO_TEST_CASE( test1 ){ 
        BOOST_CHECK(1 == 2-1); 
} 
BOOST_AUTO_TEST_SUITE_END(); 

- add a second test file using helper macros to test an other class 
(compilation is OK, link KO) : 
#define BOOST_TEST_MAIN 
#include <boost/test/unit_test.hpp> 
BOOST_AUTO_TEST_SUITE(Class2TestsSuite); 
BOOST_AUTO_TEST_CASE( test2 ){ 
        BOOST_CHECK(1 != 2); 
} 
BOOST_AUTO_TEST_SUITE_END(); 

Here are the errors : 
c:/dev/mingw/bin/../lib/gcc/i686-pc-mingw32/4.2.1-dw2/../../../../include/c++/4.2.1-dw2/new 
multiple definition of `init_unit_test_suite(int, char**)'            line 
105 
tests\main.o:c:/dev/mingw/bin/../lib/gcc/i686-pc-mingw32/4.2.1-dw2/../../../../include/boost/test/unit_test_suite.hpp 
first defined here                        line 184 

I have edited unit_test_suite.hpp to add inline decalration to 
init_unit_test_suite : 
#else 
inline ::boost::unit_test::test_suite* 
init_unit_test_suite( int, char* [] )   { 
#endif 

Doing so, first error is suppressed. I might need to rebuild boost test 
lib for the second, but I haven't the tools at workplace. 

I am using : 
- Windows XP 
- MinGW packaged with boost 1.34.1 (http://nuwen.net/mingw.html) 
- Eclipse CDT

Jérôme.
