# All PostgreSQL makefiles include this file and use the variables it sets,
# which in turn are put here by the configure script. There is no need for
# users to edit this file -- if it turns out to be necessary then that's a
# bug.
#
# A makefile that includes this file needs to set the variable `subdir' to
# the relative path from the top to itself and `top_builddir' to the relative
# path from itself to the top before including this file. (The "top" is the
# parent directory of the directory this file is in.)
