I found the following works:

Assuming an x64 Python 2.7 is used, which is installed in C:\Python27_x64.

In the repo root of a local clone of Mercurial do:

  $ C:\Python27_x64\python.exe setup.py build_ext -i
  $ C:\Python27_x64\python.exe setup.py build_hgexe -i

This should build the hg.exe and the mercurial/*.pyd files using the MS
toolchain (alternatively, this should work with --compiler=mingw32 too).

Now, copy the folder C:\Python27_x64\Lib into the repo root. Or zip its
contents to python27.zip (make sure there is no "Lib" top directory
inside the zip) and put that zip file into the repo root.

Then copy the contents of C:\Python27_x64\DLLs into the repo root
(specifically the files _ctypes.pyd, _socket.pyd, etc.).

Copy python27.dll (I found it in C:\Windows\System32 here) into the repo
root.

If you do that, setting $PYTHONHOME should no longer be needed. hg.exe
will find the things it needs right next to it.
