Oh right, the mystery continues. Maybe you'd be willing to enlighten us
further?

Ah, ok. So $(shell my-command) will never work on the Make you use? When
you say "POSIX says", I guess I should be able to find what you describe
somewhere in this file?

I'm struggling, but as far as I can tell, the POSIX standard doesn't
include any utility functions in Make. I'm not convinced that sawing off
all the useful features of GNU Make is a great idea for us.
Frankly, I am no longer interested in thinking about an unbounded number
of convoluted work-arounds to make the build work with an unspecified
tool on an unspecified platform. If you want to convince someone else to
take the patches, that's fine, but I'm probably going to ignore further
messages from you unless you tell us more about what you're trying to
do. Or you could install GNU Make? I hear it's rather portable.
