Comment (by johnmaddock):

 Well this is very strange then - I've checked that all uses of __int128 in
 Boost are guarded by BOOST_HAS_INT128 (they are), and that macro is
 defined in boost/config/compiler/gcc.hpp via:

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

 Can you try and figure out how/why BOOST_HAS_INT128 macro is getting set
 in the above code?
