No. This is not portable enough. The problem is that libstdc++'s atomic ops come with libstdc++ which precludes you from using other standard library implementations.
Perhaps I could put #define BOOST_STDLIB_LIBSTDCPP3 in <boost/config/stdlib/libstdcpp3.hpp> and then guard any use of <bits/atomicity.h> with #ifdef BOOST_STDLIB_LIBSTDCPP3.
That macro would be a good idea anyway, since otherwise detecting libstdc++-v3 requires: #if defined(__GLIBCPP__) || defined (__GLIBCXX__) There are already places that don't detect GCC 3.4's libstdc++ because they haven't been updated to check for __GLIBCXX__ as well as __GLIBCPP__. Your suggested macro would make it easier to get right. jon -- "Yield to temptation, it may not pass your way again." - Robert Heinlein
