Re: I: adjust test suite for upcoming GNU Make 3.83

[Paul D. Smith]

FYI, here's one way to handle it (obviously requires GNU make):

  ifeq (,$(filter second-expansion,$(.FEATURES)))
    # GNU make <3.81
    PRE_D := $$
  else
    # GNU make >=3.81
    PRE_D := $$$$
  endif

  # Now use PRE_D in prerequisites

  all: foo$(PRE_D)bar ; @echo '$@: $<'

  foo$$bar: ; @echo 'building $@'
