All Boost Exception tests passing here with MinGW/GCC 4.5.

With MinGW/GCC 4.6, copy_exception_test and exception_ptr_test are
failing at link time with "multiple definition of `non-virtual thunk"
errors for error_info_injector, clone_impl, error_info_injector, etc.

error_info_test is failing 8 run tests:

error_info_test.cpp(262): test '*boost::get_error_info<test_1>(x)==42'
failed in function 'void test_add_tuple()'
error_info_test.cpp(263): test
'*boost::get_error_info<test_2>(x)==42u' failed in function 'void
test_add_tuple()'
error_info_test.cpp(277): test '*boost::get_error_info<test_1>(x)==42'
failed in function 'void test_add_tuple()'
error_info_test.cpp(278): test
'*boost::get_error_info<test_2>(x)==42u' failed in function 'void
test_add_tuple()'
error_info_test.cpp(279): test
'*boost::get_error_info<test_3>(x)==42.0f' failed in function 'void
test_add_tuple()'
error_info_test.cpp(293): test '*boost::get_error_info<test_1>(x)==42'
failed in function 'void test_add_tuple()'
error_info_test.cpp(294): test
'*boost::get_error_info<test_2>(x)==42u' failed in function 'void
test_add_tuple()'
error_info_test.cpp(295): test
'*boost::get_error_info<test_3>(x)==42.0f' failed in function 'void
test_add_tuple()'
8 errors detected.

So the problems appear to affect Boost Exception too.
