[boost] [wave] test_re2c_lexer / V2

Hi, the test_re2c_lexer test of Wave fails under msvc-7.1/Boost.Build V2, as shown at: http://tinyurl.com/joupe The error says that dllimport/dllexport directives are wrong. This was not detected with V1, but V2 uses shared linking by default and so detects the problem. In other words, it's possible that the re2c lexer cannot be used when Wave is built as DLL. Hartmut, can you look into this? - Volodya
