Building on Windows

[Sam Ezeh]

I have a Windows virtual machine and I'm following the instructions on
the devguide [1] to build Python inside it.

When running `PCbuild\build\bat -e -d` I get "Cannot locate
MSBuild.exe on PATH or as MSBUILD variable". I've done a minimal
amount of searching [2][3] but I'm not well-acquainted with Windows
and don't understand the solutions.

Thanks in advance.

Kind regards,
Sam Ezeh
