It's possible to do that instead of what I did. I simply am not sure
this is what the users will want.
Does someone else here have an opinion? If so, please speak up.

Here's an example. Suppose the current directory on drive D: is
initially d:/foo. Now, consider this Makefile:
BAR = $(abspath d:bar)
all:
make -C d:/fubar mumble
make BAR=$(BAR)
Since the first command changes PWD on drive D:, the second command
will do a "make BAR=d:./bar" with my code, which is the equivalent of
"make BAR=d:/fubar/bar". OTOH, with your suggestion it will do a
"make BAR=d:/foo/bar" instead.
As I say above, I'm not sure what is the right way; I could go with
either one. Opinions (and reasons) are highly appreciated. TIA
