[issue37167] Cannot build Windows python_d.exe in master branch

[Terry J. Reedy]

New submission from Terry J. Reedy <tjreedy at udel.edu>:

In master, pcbuild/build -e -d (the 2nd run) gave the errors in build_errors.txt. Many or most were like

f:\dev\3x\externals\xz-5.2.2\src\liblzma\common\block_encoder.h(1): error C2018
: unknown character '0x2' [F:\dev\3x\PCbuild\liblzma.vcxproj]

>chkdsk found no problems.

A fix is high priority for me because my most recent 3.8.0a4 build in master, on 6/2, no longer imports tkinter.  Hence IDLE fails also.

>>> import tkinter
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "F:\dev\3x\lib\tkinter\__init__.py", line 36, in <module>
    import _tkinter # If this fails your Python may not be configured for Tk
ImportError: Module use of python39_d.dll conflicts with this version of Python.

Building python_d.exe for 3.8 and 3.7 had no problem.
