Hello,
when using /DBOOST_USE_WINAPI_VERSION=0x0602 /D_WIN32_WINNT=0x0602 /DWINVER=0x0602 or higher, the build of Boost.Log fails due to linker errors involving two missing symbols, WaitOnAddress and WakeByAddressSingle. These functions were introduced in Windows 8, i.e. 0x0602, and according to MSDN, their import library is synchronization.lib. This library is not mentioned on the linker command line or any build system files.
I added it to build/Jamfile.v2 and the library built successfully, but I'm far from an expert in Boost's build system. I'm also doing everything via vcpkg, which probably introduces even more unpredictability.
