11833,Boost usage of __int128 when compiled with clang-cl,Yaron Keren <yaron.keren@…>,John Maddock,"Boost compiled with clang-cl targetting MSVC toolchain should not probably use __int128 as the support functions __umodti3 and friends, usually available from libgcc are not available from the MSVC libs leading to error LNK2019: unresolved external symbol __umodti3.

This may be solved either by using compiler-rt along with the MSVC libs or by not defining BOOST_HAS_INT128 in clang.hpp:

#if defined(__SIZEOF_INT128__) && !defined(__CUDACC__) && !defined(_MSC_VER)
#  define BOOST_HAS_INT128
#endif

I'm not sure which is the right way to go here, but this should be at least be documented.
