FYI: fetch config-ml.in and symlink-tree from GCC.

 adl> I'll wait for GCC's PR/11526 to be fixed before adding
 adl> symlink-tree and config-ml.in to `make fetch'.

I'm checking this in on HEAD and branch-1-7.

2003-07-29  Alexandre Duret-Lutz  <address@hidden>

        * Makefile.am (FETCHFILES, fetch): Add config-ml.in and
        symlink-tree.
        * lib/config.sub, lib/config-ml.in, lib/texinfo.tex: New
        upstream versions.
