[Segev Finer]

New submission from Segev Finer:

We are getting:

Warning	C4005	'HAVE_MEMMOVE': macro redefinition	_elementtree	c:\users\segev\prj\python\cpython\modules\expat\winconfig.h	34	
Warning	C4267	'=': conversion from 'size_t' to 'unsigned char', possible loss of data	_elementtree	c:\users\segev\prj\python\cpython\modules\expat\siphash.h	316

And in 64-bit:

c:\users\segev\prj\python\cpython\modules\expat\siphash.h(201): warning C4244: 'initializing': conversion from '__int64' to 'char', possible loss of data

I'm not sure how many Python versions this affects.
