[cmake-developers] _PyPopenProcs warning and comment in cmWin32ProcessExecution.cxx

[Stephen Kelly]

Hi there,

http://open.cdash.org/viewBuildError.php?type=1&buildid=2652291

has a new warning (as a result of my adding warning flags) of an unused 
variable. The variable is referenced in a comment. I'm guessing a snippet 
came from elsewhere. 

I can remove the _PyPopenProcs variable, but I think the comment should be 
fixed too at the same time. However, I don't know what the comment should be 
changed to.

Can someone else take over that task?

Thanks,

Steve.
