using latest VS2010 and llvm/clang 10.0.0 release (10.0.1 is a litte bit more recent but no windows builds available)

Aside: WinLibs standalone build of GCC and MinGW-w64 for Windows at Winlibs.com has very recent builds, mainly intended for Mingw-64, but often OK for Windows clang-cl too? (I am using Clang and GCC from this site with CodeBlocks IDE and also using b2/bjam but I could not get the clang-win .exe to build reliably and am using clang-linux .exe in my user-config.jam. However this isn't any help to your difficulties ☹ ).

compiler set to 2017 microsoft-cl in VS2017: libboost_serialization-vc141-mt-gd-x32-1_74.lib

compiler set to clang-cl in VS2017: libboost_serialization-clangw10-mt-gd-x32-1_74.lib

that behavior is new to 1.74 - older boosts versions 1.69..1.73 would use the vc141 libs what makes sense because clang-cl is the microsoft-cl compatible replacement

normaly there is no need to switch any external libs when using clang-cl instead of microsoft-cl
