Windows is horrible with it's command line processing.  Add on top of  
that, the system call to create a process takes a single string -- so  
there is no way to specify arguments exactly without using quotes,  
equivalent to Unix exec.

Take a look at a proposed new version of std.process, and you can see my  
trial-and-error analysis of the windows command line processing engine.

Note, please do not try using the new version of std.process on Windows --  
it requires fixes to the DMC runtime (given to Walter already).
