I'm trying to construct a system that reinvokes make 3.81 if
make 3.80 is initially used to attempt a build. I've attached
a testcase showing the general structure.
Make 3.80 complains about a missing endif. Why?

define invoke_correct_make_impl
$(warning here 2.1)
.SUFFIXES:
.PHONY: invoke_correct_make

all:

GNU make 3.81 --should get PASSED))

include second.mk
