Regarding 2017 POSIX says
POSIX.1-2008, POSIX.1-2017, and Single UNIX Specification, Version 4
_POSIX_VERSION == 200809L, plus (if the XSI option is
supported) _XOPEN_UNIX and
_XOPEN_VERSION == 700
Note that _POSIX_VERSION did not change in POSIX.1-2017 as it
was technically identical to POSIX.1-2008 with its two
technical corrigenda applied.

And, fwiw..
For make files ipersonally and in the past .. even generated them
via perl (completely that is); today the "big" published thing
still does so with awk etc (inference rules i never got truly
right, but, if i do, they then show limitations at times (certain
flags needed for certain files, or what)). *But* i started to
rarely use constructs like ?= in certain small things (ie i *want*
some make flags, but the user *wants* to add additions, so mostly
optimization and debug one can pass in to the makefile to the
outside), where there shall be nothing but a makefile.
That += this thread was about in particular seems to be pretty
portable, as i think in practice you end up with only GNU make,
(Free|Net)BSD make and OpenBSD make.
Sure, Solaris stuff cannot, but on the Solaris systems i can get
my hands on there is always GNU make installed.

See the man page dmake(1) for more information on setting up the .dmakerc

But this works:
