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
4 # but tell the user to use GNU make.
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".
11 # AIX make defaults to building *every* target of the first rule. Start with
12 # a single-target, empty rule to make the other targets non-default.
