1. run this:
    path_to\vcvars32.bat && devenv solution_file.sln /rebuild "Release"

2. create a wrapper batch file with those two lines and run the new
   batch file:
        ---- temp.bat -------
        path_to\vcvars32.bat
        devenv solution_file.sln /rebuild "Release"
        ---------------------
   
   fout = os.popen('temp.bat')


Cheers,
Trent
