_______________________________________________________
Details:
If one wants to simulate ?= for singly expanded variables, one has to write
ifeq ($(origin FOO), undefined)
FOO := bar
endif
and doing that repeatedly is abit of a pain...
I'm using 3.80, but reading the NEWS for 3.81 shows that this is not there
either.
