I attempted to run Clang 3.4.1 on Win 8.1 with horrible results as evident on the current master regression summary here: http://www.boost.org/development/tests/master/developer/summary.html Besides the fact that boost identifies it as linux clang and there appears to be numerous other issues with the b2 script, has anyone had any success with this? The reason I ask is AMD is using LLVM for their heterogeneous development and I'm trying to see if boost will be something I can count on. Thanks, -Matt
