Boost\libs\python failed to build due to link error on MSVC

Reproduisez l’échec depuis une invite de commandes VS 2019 x64 en utilisant .\bootstrap, les deux commandes de build .\b2 et la commande finale .\b2 ... libs\python\test. Examinez la réponse de l’édition de liens générée et la configuration de build de Boost.Python ; c’est terminé lorsque le build MSVC signalé et la cible de test sont liés avec succès.

Issue description:
Boost\libs\python failed to build due to link error on MSVC. Could you please take a look?

Build step:

1. git clone -c core.autocrlf=true --recursive ​https://github.com/boostorg/boost.git D:\Boost\src
2. open a VS 2019 x64 command prompt and browse to D:\Boost\src
3. .\bootstrap
4. .\b2 headers variant=release --build-dir=..\out\x64rel address-model=64
5. .\b2 variant=release --build-dir=..\out\x64rel address-model=64
6. .\b2 -j4 variant=release --build-dir=..\out\x64rel libs\python\test
