#if __GNUC__ < 3 # define BOOST_GCC BOOST_JOIN(__GNUC__,__GNUC_MINOR__) #else # define BOOST_GCC BOOST_JOIN( BOOST_JOIN(__GNUC__,__GNUC_MINOR__),__GNUC_PATCHLEVEL__) #endif
This should work until second or third component is < 10.
What about gcc-2.95 ?
Also appropriate print added into confg_info.
Anybody mind?
I think I would have preferred a more consistent numbering system - a bit like BOOST_VERSION maybe: #define BOOST_GCC (__GNUC__*10000 + __GNUC_MINOR__ * 100 + __GNUC_PATCHLEVEL__) Of course even that can in theory go wrong, but it does make checks easier to read (because of greater consistency between gcc 2 and 3): #if BOOST_WORKAROUND(BOOST_GCC, <= 29500) #else BOOST_WORKAROUND(BOOST_GCC <= 30400) // etc.... Any other thoughts? John.
