The entering/leaving messages are entirely unrelated, as they don't
involve expanding Make variables.

Could it be that those that are downcased are all in quotes?

Maybe try a newer one.

But all the reconfiguration does is regenerate Makefile's, and you say
they all come out OK.

And reconfiguration is triggered very often these days, so you should
have seen this more frequently.

Perhaps you should always create a log of a build (e.g., with 'tee'),
and collect those that fail like this.  Then, when you have a few, we
could see what do they have in common.

I think it's just a subtle bug, all it is.
