Description
VS apparently does not define stream operators for std::pair. Compiling map.cpp results in:
map.cpp
1>d:\boost\boost_1_61_0_b1\boost\test\tools\detail\print_helper.hpp(47): error C2338: Type has to implement operator<< to be printable

One way to eliminate this problem is to add the following to the top of map.cpp:
typedef std::pair<const std::string, int> str_int_map_type;
BOOST_TEST_DONT_PRINT_LOG_VALUE(StructBase)
BOOST_TEST_DONT_PRINT_LOG_VALUE(str_int_map_type)
