cd libs\system\test

..\..\..\b2 address-model=64 toolset=msvc-12.0 -a cxxflags=-W4 is not producing any warnings.

Please supply instructions to reproduce the problem. What platform macros are defined? What version of the compiler?

Here's a build log: ​https://ci.nedprod.com/view/Boost%20Thread-Expected-Permit/job/Boost.Thread%20Build/CPPSTD=c++14,CXX=msvc-12.0,LINKTYPE=shared,label=winphone8/64/console

To reproduce, you'll need VS2013 and the Windows Phone SDK installed:

b2 address-model=64 toolset=msvc-12.0 windows-api=store release -a libs/thread/build link=shared cxxflags=/wd4100
