And the reason seems to be is that it's considered the latest "release" version.

In the git tree, I see 4.2.92, but looking at

    https://ftp.gnu.org/gnu/make/

it looks like 4.2.1 is the latest actual "release".

Oh well. I can't find a workaround for the bug, other than perhaps
using "make -LX" instead of "make -jX". Which is not the same thing at
all, of course.
