Comment (by mgaunard):

 on the Windows platform clang uses the code path in platform/win32.hpp.
 clang supports both `__attribute__` and `__declspec`.

 What I'd recommend is to put in compiler/clang.hpp the following

 {{{
 #if defined(_WIN32) || defined(__WIN32__) || defined(WIN32))
 #define BOOST_SYMBOL_EXPORT __attribute__((__visibility__("default")))
 #define BOOST_SYMBOL_IMPORT
 #define BOOST_SYMBOL_VISIBLE __attribute__((__visibility__("default")))
 #endif
 }}}
