You're making the same point I was thinking about earlier, which is that in theory #pragma once shouldn't be faster than include guards. So how about this:
#include <boost/detail/workaround.hpp> #if defined(BOOST_MSVC) && BOOST_WORKAROUND(BOOST_MSVC, < 1500) #pragma once #endif
Other than the fact that this should just be solved for once and for all in MSVC, rather than forcing us to pollute our code, I don't see a problem with just using this:
#ifdef BOOST_ENABLE_PRAGMA_ONCE #pragma once #endif
I'm not sure you got my drift, using BOOST_WORKAROUND effectively flags the better #pragma once performance on MSVC as a bug. :) Emil Dotchevski Reverge Studios, Inc. http://www.revergestudios.com/reblog/index.php?n=ReCode
