 boost/config/compiler/gcc.hpp defines BOOST_SYMBOL_VISIBLE and
 BOOST_SYMBOL_EXPORT to be __attribute__((visibility("default"))) when not
 running under Windows.  But boost/config/compiler/clang.hpp does not
 define these symbols.  This creates compatibility problems on OS X when
 linking binaries built with gcc to binaries built with clang.  Since clang
 is used as a replacement for gcc, I would expect that BOOST_SYMBOL_VISIBLE
 and BOOST_SYMBOL_EXPORT should be defined in the same way for clang.
