It's useful to have
#ifndef __has_feature #define __has_feature(x) 0 #endif

in suffix.hpp so that one can then use __has_extension(foo) everywhere without fear. Otherwise, even
#if defined(__clang__) && defined(__has_extension) && __has_extension(foo)
is a preprocessor error when __has_extension is not defined (which it isn't when not on Clang.)
Good point.
However, aren't those reserved symbols? If we're being pedantic....
I was going to point out the same. What about BOOST_HAS_FEATURE and BOOST_HAS_EXTENSION? ___ Rob (Sent from my portable computation engine)
