1# The Postgres make files exploit features of GNU make that other makes
2# do not have.  Because it is a common mistake for users to try to build
3# Postgres with a different make, we have this make file that does nothing

6# If the user were using GNU make now, this file would not get used because
7# GNU make uses a make file named "GNUmakefile" in preference to "Makefile"
8# if it exists.  Postgres is shipped with a "GNUmakefile".
