| | | | | | | | | | | | | | | | | | | | | | | | | | | As stated in PEP 11, 3.4 removes code on Windows platforms where COMSPEC points to command.com. The w9xpopen project in Visual Studio was added to support that case, and there was a special case in subprocess to cover that situation. This change removes the w9xpopen project from the Visual Studio solution and removes any references to the w9xpopen executable.
