Thanks for asking. As I don't recall having run into the specific
problem mentioned above, I suppose I've given up at some
point and forced the use of a newer make even on those very
old distros that I tend to build / test stuff on every once in a
while. IOW I guess I'm fine with the proposed change, and I
can help myself if nevertheless needed.
