The rest of the PR cares about deprecation warnings like

..\Modules\socketmodule.c(6070,9): warning : 'gethostbyname' is deprecated:
Use getaddrinfo() or GetAddrInfoW() instead or define _WINSOCK_DEPRECATED_NO_WARNINGS
to disable deprecated API warnings [-Wdeprecated-declarations]

using the already existing infrastructure _Py_COMP_DIAG_PUSH et al. from pyport.h, because clang-cl unfortunately does not (yet) respect
