Sorry for not being more clear.  The WDK provides build.exe, a utility
that calls the compiler & linker with the approprite switches.  In
essence, it manages all the nmake details away from the developer.
For some, this is a bad thing in terms of loss of control.  But in
reality, this is a great thing, as this is the way Microsoft builds
Windows.  As far as I can tell, the WDK build environment is dervied
from the Microsoft Windows build environment, which is great for
developing kernel components in the similar enviornment in which
Microsoft builds its OS.  It is a requirement to use the WDK.

Setenv.bat sets up the path and other environment variables build.exe
needs to compile and link (and even binplace) its utilities.  So
building itself is not the issue.  The problem is that if I call
setenv.bat from Python and then build.exe, but the modifications to
the path (and other environment settings) are not seen by Python, so
the attempt to build without a specified path fails.

Now I can open up a build window that targets a build type (check or
release), an architecture target (x86 or x64) and an OS target (which
will be Windows Xp except if in the future, the driver(s) uses some
infrastructure introduced in later versions of WDM.

However, what I was hoping to do was to have a python script that
would allow me to build 4 versions of the driver: x86 check, x86
release, x64 check, and x64 release.  I may have to resort to using
batch files, but I was hoping as much as possible to use Python.

Thanks,
Kosta
