I did not find this discussion.

I added following into gcc.hpp:

#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.

Also appropriate print added into confg_info.

Anybody mind?
