Ok- hopefully that's true for the version mentioned in the subject line.

Test1.cpp:
-----
#include "stdafx.h"

#define BOOST_TEST_MODULE foo2

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

class DefaultFixture {
public:
    DefaultFixture()
    {
    }
    ~DefaultFixture() {};
};

BOOST_AUTO_TEST_SUITE(foo2)

BOOST_FIXTURE_TEST_CASE(foo2, DefaultFixture)
{
     BOOST_CHECK(4 == 4)
}
-----
Test2.cpp:
-----
#include "stdafx.h"

#define BOOST_TEST_MODULE foo

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

class DefaultFixture {
public:
    DefaultFixture()
    {
    }
    ~DefaultFixture() {};
};
BOOST_AUTO_TEST_SUITE(foo)

BOOST_FIXTURE_TEST_CASE(foo, DefaultFixture)
{
    BOOST_CHECK(4 == 4);
}
BOOST_AUTO_TEST_SUITE_END()

And Link with boost library....

1>TestCase2.obj : error LNK2005: "class boost::unit_test::test_suite * __cdecl init_unit_test_suite(int,char * * const)" (?init_unit_test_suite@@YAPAVtest_suite_at_unit_test_at_boost@@HQAPAD_at_Z) already defined in basic.obj

Googling around, I discovered this cryptic define done in one of the files will fix it:
-----
#define init_unit_test_suite init_auto_unit_test_suite
-----

A strange observation as well....

Take this code:

#include "stdafx.h"

#define BOOST_TEST_MODULE foo

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

class DefaultFixture {
public:
    DefaultFixture()
    {
    }
    ~DefaultFixture() {};
};
BOOST_AUTO_TEST_SUITE(foo)
BOOST_FIXTURE_TEST_CASE(foo, DefaultFixture)
{
    BOOST_CHECK(4 == 4);
}

BOOST_AUTO_TEST_SUITE_END()

And change BOOST_FIXTURE_TEST_CASE toBOOST_TEST_CASE(foo)... it won't compile:

C:\basic\test2.cpp(21) : error C2882: 'foo' : illegal use of namespace identifier in expression
c:\code\main\test\bora-vmsoft\svga\tests\bat\basic\basic\test2.cpp(22) : error C2448: 'boost::unit_test::make_test_case' : function-style initializer appears to be a function definition

    Anyway, thanks for your help. The documentation right now seems to be lacking a little bit in giving clear examples of the different styles in which we are able to do test and suite registration.
