Hi Arushi,

OSProcess support for Windows is not as complete as it should be,
so some of the things that work on Linux do not work properly on
Windows. It looks like you have successfully built an OSProcessPlugin
for your Windows system (well done!). I do not have a Windows system
with me today and I have not looked at this in a while, but I am
afraid that passing command line arguments may be one of the things
that is not complete on Windows.

Another thing that could be an issue is that the OS pipe support
on Windows does not work, so on Windows you cannot read and write
the input and output streams to the external Squeak process that
you are starting. I don't know it that is a concern for you or not.
