non-executable install-sh

[Patrick Welche]

Is this worth adding

diff --git a/lib/autoconf/programs.m4 b/lib/autoconf/programs.m4
index 63f8a13..370ed31 100644
--- a/lib/autoconf/programs.m4

-    MKDIR_P="$ac_install_sh -d"
+    MKDIR_P="\$(SHELL) $ac_install_sh -d"
   fi

 dnl status.m4 does special magic for MKDIR_P instead of AC_SUBST,



to work around the unfortunate situation where install-sh looses
its executable bit when an archive is unpacked incorrectly?
