+# The Postgres make files exploit features of GNU make that other makes
+# do not have. Because it is a common mistake for users to try to build
+# Postgres with a different make, we have this make file that does nothing
+# but tell the user to use GNU make.
+
+# If the user were using GNU make now, this file would not get used because
+# GNU make uses a make file named "GNUmakefile" in preference to "Makefile"
+# if it exists. Postgres is shipped with a "GNUmakefile".
