There's currently a test case for Boost.Integer failing in MSVC ++ 6.0 with a LNK1179 error: http://tinyurl.com/8rpuu This bug in MSVC++ 6.0 shows when the compiler emits different symbol names with a very long common prefix: in this particular case, the offending symbol names are generated by a couple of BOOST_CHECK instantiations. The proposed patch works around the problem and only affects to the test code, not the library, so I guess it's safe enough. OK to commit?
