+Re-compilation of the base sets, thus also use of --maintainer-clean can
+leave the repository in a modified state as different grfcodec versions can
+cause binary differences in the resulting grf. Also translations might have
+been added for the base sets which are not yet included in the base set
+information files. Use the configure option --without-grfcodec to avoid
+modification of the base set files by the build process.
