+	Make --enable-relocatable work with DESTDIR.
+	* build-aux/install-reloc: Accept another argument 'destdir'. Use it
+	to compute installdir from destprog.
+	* m4/relocatable.m4 (gl_RELOCATABLE_BODY): In INSTALL_PROGRAM_ENV,
+	also set the RELOC_DESTDIR variable.
+	Reported by Левашев Иван <octagram@bluebottle.com>.
