I'm surprised by the test_codecencodings_iso2022 failures. Example:
======================================================================
FAIL: test_incrementaldecoder (test.test_codecencodings_iso2022.Test_ISO2022_KR)
----------------------------------------------------------------------
Traceback (most recent call last):
File "E:\GitHub\cpython\lib\test\multibytecodec_support.py", line 208, in test_incrementaldecoder
self.assertEqual(ostream.getvalue(), self.tstring[1])
AssertionError: b'\xe[334 chars]\x80\n\xed\x9a\xa8\xec\x9c\xa8\xec\xa0\x81\xec[1668 chars]4.\n' != b'\xe[334 chars]\x80\r\n\xed\x9a\xa8\xec\x9c\xa8\xec\xa0\x81\x[1682 chars]\r\n'
It looks like Python uses the wrong encoding to decode stdout of child processes:
======================================================================
ERROR: test_build_ext (distutils.tests.test_build_ext.BuildExtTestCase)
----------------------------------------------------------------------

return codecs.charmap_decode(input,self.errors,decoding_table)[0]
UnicodeDecodeError: 'charmap' codec can't decode byte 0x90 in position 49: character maps to <undefined>
It would help to add a print() to lib\distutils\_msvccompiler.py:92 to get the executed command, then run manually the command, and see non-ASCII characters in the output.
