[Boost-users] Wave doesn't recognize c++0x keywords ?

Hi, I'm new to Boost.Wave. I followed the "quick start", but found that wave take the C++0x keyword "decltype" as an identifier instead of a keyword. The macro "BOOST_WAVE_SUPPORT_CPP0X" is defined as "1". Boost version: 1.47.0 Any suggestions ? Thanks. -Yao
