+dnl These odd looking assignments are done to expand out unexpanded
+dnl variables in bindir et al (for instance mandir is '${datarootdir}/man',
+dnl but expanding that gives '${prefix}/share/man', so we need to expand
+dnl again to get the final answer.
+dnl We only use the expanded versions to print the install paths in
+dnl the final summary and should use them nowhere else (see the autoconf
+dnl docs for the rationale for bindir etc being unexpanded).
