GNU Make version 3.05 can put seemingly bogus values for string variables
into the environment when running programs.  It can be worked around by putting
them explicitly into the environment (for example, VPATH=$(VPATH)), but it
worked properly before.  /bin/make is GNU make 3.05; /bin/OLDgmake is GNU make
from mid July (sorry, I don't know the version).
