+dnl CF_MAKE_PHONY version: 3 updated: 2021/01/08 16:08:21
+dnl -------------
+dnl Check if the make-program handles a ".PHONY" target, e.g,. a target which
+dnl acts as a placeholder.
+dnl
+dnl The ".PHONY" feature was proposed in 2011 here
+dnl     https://www.austingroupbugs.net/view.php?id=523
+dnl and is scheduled for release in P1003.1 Issue 8 (late 2022).
+dnl
+dnl This is not supported by SVr4 make (or SunOS 4, 4.3SD, etc), but works with
+dnl a few others (i.e., GNU make and the non-POSIX "BSD" make):
+dnl
+dnl + This is a GNU make feature (since April 1988, but in turn from binutils,
+dnl   date unspecified).
+dnl
+dnl + It was adopted in NetBSD make in June 1995.
+dnl
+dnl + The other BSD make programs are derived from the NetBSD make (and for
+dnl   that reason are not actually different "implementations").
+dnl
+dnl + Some features of NetBSD make were actually adapted from pmake, which
+dnl   began as a modified GNU make starting in 1993.
+dnl
+dnl + Version 3.8 of the dmake program in January 1992 also implemented this
+dnl   GNU make extension, but is less well known than the BSD make.
