It may be interesting to add the compiler version to test.pythoninfo. It would be simpler to compare Windows buildbots to identify a bug.

Currently, the only info is:

"sys.version: 3.7.0a4+ (heads/master:9d411c1, Jan 23 2018, 15:13:42) [MSC v.1900 32 bit (Intel)]"

Some environment variables are also dumped:

os.environ[VS100COMNTOOLS]: C:\Program Files\Microsoft Visual Studio 10.0\Common7\Tools\
os.environ[VS140COMNTOOLS]: D:\Program Files\Microsoft Visual Studio 14.0\Common7\Tools\
os.environ[VS90COMNTOOLS]: D:\Program Files\Microsoft Visual Studio 9.0\Common7\Tools\

In the compile step, I see lines like:

"Microsoft (R) Build Engine version 14.0.24730.2"

I recall also issues with outdated ucrtbase DLLs. Maybe we can also dump the version of such DLL?
