You mean that for certain versions of make one should use
`export CDPATH=' instead of just `CDPATH='?

The `make' manual seems to say that variables exported to make from
the environment are automatically exported to sub-make's anyway and,
moreover, at first view it would seem to not make any difference
whether CDPATH is the empty string or not defined at all.

Or do some versions of make actually reinitialize environment
variables directly from the shell environment that invoked make for
sub-make's if not exported?

Anyway, it would seem like the `export' can not do any harm, even
though I do not immediately understand how it could do some good.
(But I know very little about Makefiles).
