 2009-01-17  Bruno Haible  <bruno@clisp.org>
 
+       Support for stripping executables in --enable-relocatable.
+       * build-aux/install-reloc: Expect one more argument, or an environment
+       variable RELOC_STRIP_PROG. If set, strip the destination program and
+       its wrapper.
+       * m4/relocatable.m4 (gl_RELOCATABLE_BODY): In INSTALL_PROGRAM_ENV, set
+       RELOC_STRIP_PROG.
+       * doc/relocatable-maint.texi (Supporting Relocation): Mention the need
+       to set RELOCATABLE_STRIP.
+       * NEWS: Mention the new Makefile requirement.
+
+2009-01-17  Bruno Haible  <bruno@clisp.org>
+
        * build-aux/install-reloc: Remove debugging information left over by
        C compiler on MacOS X.
