# 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".


# AIX make defaults to building *every* target of the first rule.  Start with
# a single-target, empty rule to make the other targets non-default.
