It seems to me that the compile error isn't caused by Boost.PreProcessor.
Actually I think I've found a workaround: Explicitly qualify the
shared_library::get member function call in extension/convenience.hpp (line 29),
(by adding the class name, "shared_library::") and the MSVC 7.1 error message
disappears!
