I think you're missing a point here.
Your knowledge or management limitations will not have any effect whatsoever
on anyone who works on Cygwin.
I'm telling you that your best bet is to fix your problem yourself
because it is unlikely that anyone else is going to do it for you.
I'm not trying to be mean. I'm just telling you what your options are.

You can use the word "surely" a few more times but it isn't likely that
you are going to find a magic bullet for your problem.
