dulwich on Windows 7 (not)

[Ernie Rael]

Ah, now I remember... dulwich, and I guess upcoming hg-git 0.9 aren't 
python 2.7 on windows compatible.

On windows 7, running python 2.7.18. Several tools I use, in particular 
mercurial and extensions, aren't quite 3.8 ready as far as I've heard. 
At least the binaries I install for Mercurial have an embedded python 2.7.

Are they ready for python 3.8?

A few months ago I did install "Microsoft Visual C++ Compiler Package 
for Python 2.7. But the install of dulwich fails when building. Can't 
find 'stdint.h', see below. Searching around seems to indicate I'm using 
an old c compiler; well, that's true.

Seems to be a catch-22. I need python 2.7, and the required compiler is 
too old for dulwich 0.20. And dulwich 0.20 is required for the soon to 
be latest hg-git.

See https://wiki.python.org/moin/WindowsCompilers/ for reference

Including dulwich binaries with hg (plain or Tortoise) would be greatly 
appreciated, at least until hg binaries are released with a modern 
python; assuming the required uSoft compiler will compile dulwich.
