In my quick search, I found only a note that "many checks" > cache their results. It _is_ documented, albeit a little implicitly. info Autoconf 'Cache Variable Names' mentions, how the cache names are built, and info Autoconf 'Macro Names' mentions the types, for example `PROG' and `PATH'. Reading that, plus observing that the corresponding cache names _are_ used would make /me/ innocent user believe they were safe to use.
