Most importantly, it cannot be an exclusion rule: Cygwin must contain things not in POSIX.

That just created a Standard in the XKCD sense: > > https://xkcd.com/927/ Thanks, Warren, for some metaphysical insights :) Right, there isn't and shouldn't be a strict rule. But maybe there can be a guideline, and more a guideline of common practice than of a 15th standard. By decade-long practice as a Unix user, I was simply expecting cmp to be basic, like I would expect tar. Maybe others would agree with that, or maybe not...
