-# This file is a shell script that caches the results of configure
-# tests run on this system so they can be shared between configure
-# scripts and configure runs. It is not useful on other systems.
-# If it contains results you don't want to keep, you may remove or edit it.
-#
-# By default, configure uses ./config.cache as the cache file,
-# creating it if it does not exist already. You can give configure
-# the --cache-file=FILE option to use a different cache file; that is
-# what configure does when it calls configure scripts in
-# subdirectories, so they share the cache.
-# Giving --cache-file=/dev/null disables caching, for debugging configure.
-# config.status only pays attention to the cache file if you give it the
-# --recheck option to rerun configure.
