The following observations were made of the PCBuild8 solution:

1  pyproject.vsprops was missing usermacros for tcltk / msi
2  no vcproj for ssl module like the PCBuild solution has
3  _msi project did not havea valid includedir
4  _tkinter did not have a valid includedir


Suggested Changes:


1  I would like to suggest adding macros such as the following to the
pyproject.vsprops.  These could then be referenced throughout the
associated projects.

<UserMacro
  Name="tcltkDir"
  Value="..\..\..\tcltk"
/>
<UserMacro
  Name="msinstDir"
  Value="C:\MsiIntel.SDK\"
/>

Reasoning: To continue to promote pyproject.vsprops as being an
almost-one-stop-shop for setting relative locations of third party
libraries.  This can be done in the following way:

- tcltkDir could be used to add a valid includedir to the _tkinter project
- msinstDir could be used to add a valid includedir to the _msi project.


2  no vcproj for ssl module like the PCBuild solution has

See: pcbuild8_for_ssl.patch... The only thing left to do is add the
associated _ssl project to the vsproj.

Reasoning: To let their be a way to build the ssl module.

Note: I suppose there could have been good reason for not putting in the
_ssl module, since it uses a support .bat / .py to build (but that's for
better people to decide)


3 If 1 is satisfied, a standard includedir variable could be added


4 If 1 is satisfied, a standard includedir variable could be added


I am hesitant to submit a full patch for all of these here, since it may
be decided that some of these be treated as separate issues.  If a full
patch is desired I can submit one.
