I am still not sure what these intermediate manifest files do. I do know that some of our programs failed when I turned it off in compilation. So, of course, I restored it.
Today when I was compiling a program, I noticed (or properly paid attention to) a message to the effect that it was "embedded"/ Whatever it does, could it be that I don't need it as a companion file alongside the executable? I have, up to now, been including the intermediate manifest file in the same folder as the executable in the belief that it is needed there. I am wondering now if the embedding means that it becomes part of the executable.
