Over the weekend, I realized that the rule can’t be that simple, because that would drag in GCC.

The problem, of course, is that there is no common practice.

I think the closest parallel to the Cygwin Base philosophy is the minimal or base installs of several other *ixes, particularly the BSDs.  It is also something like a throwback to the SysV Unixes, prior to about 1992, when you could count on things like X and the C compiler to be separate installs.

But even that guideline isn’t especially useful, since often such OSes *do* include the C compiler and all its support tooling.

Ultimately, I think Cygwin Base is whatever Corinna and Yaakov say it is. :)
