As per
<http://thread.gmane.org/gmane.comp.sysutils.autoconf.patches/6880>,
we should avoid \{M,N\} after \(...\) for Solaris /bin/sed. I found
only one instance in the Libtool code base, pushing the patch below
to fix it; alongside, simplifying the quoting here.
Cheers,
Ralf
Fix func_normal_abspath sed script for Solaris.
* libltdl/config/general.m4sh (pathcar, pathcdr, removedotparts)
(collapseslashes, finalslash): Use single quotes, for clarity.
(removedotparts): Avoid \{N,M\} after subexpression \(...\), for
Solaris /bin/sed.
