Hi, I'm trying to compile Boost 1.37 with PGI 7.0-7 (which does not support some SSE2 instructions, but this is easily managed) and I run into a missing ";" in archive/codecvt_null.hpp when no STD namespace is available: 25 #if defined(BOOST_NO_STDC_NAMESPACE) 26 using ::codecvt; 27 using ::mbstate_t; 28 using ::size_t 29 #endif Line 28 should end with a comma.
