I'd say that make itself is sloppy wrt whitespace, where sometimes
newlines are considered to be whitespace, othertimes not.

For example, as you reported, gmake's $(strip ...) function treats
newlines as whitespace.  But the "word" family of functions do not.

    define x

            echo $(words $(x))
            echo $(words $(strip $(x)))

Given a choice, I'd prefer the word functions treat newlines as
