In most packages that is probably the best solution. However, maybe I'm
just stubborn, but I tend to be a little more conservative with GNU make
(it still compiles with K&R compilers even!) because it's an integral
part of the bootstrap chain.
However, probably within a few years I'll be willing to let go of these
really old systems even in GNU make--they can always use an older
version to bootsrap, after all :).

Hm, not a bad idea. The comments say this was a problem on "System V
before release 3". Unfortunately I have no idea how to test that based
on the system type.
