This trick seemed to work at first, but then when I ran the 1.37.0
test tests I got:

..\..\libs\test\example\unit_test_example_10.cpp(75) : error C2039:
'check_is_close' : is not a member of 'boost::test_tools'
..\..\libs\test\example\unit_test_example_10.cpp(75) : error C2065:
'check_is_close' : undeclared identifier

Other ideas? I need to patch 1.37.0 to kill these warnings.

Thanks,
Mat
