Message 353191 - Python tracker

This line in _tesctcapimodule.c:
    {"__dictoffset__", T_PYSSIZET, -sizeof(void*), READONLY},

gives a legitimate-sounding warning on a Windows buildbot:

         d:\buildarea\3.x.ware-win81-release.nondebug\build\modules\_testcapimodule.c(6409): warning C4146: unary minus operator applied to unsigned type, result still unsigned [D:\buildarea\3.x.ware-win81-release.nondebug\build\PCbuild\_testcapi.vcxproj]
