Building code (on Solaris, OmniOS, and SmartOS, using gcc) which includes boost, produces warnings such as the following:

In file included from src/boost/config/platform/solaris.hpp:17:0,
                 from src/boost/config.hpp:57,
                 from src/boost/cstdint.hpp:36,
                 from src/code_that_includes_boost.cpp:43:
src/boost/config/posix_features.hpp:27:0: warning: "BOOST_HAS_STDINT_H" redefined [enabled by default]
 #        define BOOST_HAS_STDINT_H
 ^

Not a big deal, but figured I’d report it in case it hadn’t been reported yet.
