FYI: 117-gary-libltdl-installtime-timestamps.patch

[Gary V. Vaughan]

Applied to HEAD and branch-2-0.

Even with {115.116}-gary-* applied, the installed
$prefix/share/libtool/libltdl tree wasn't preserving timestamps
as libtool was installed.  So time based dependencies would still
trigger spuriously in the users tree after libtoolize --copy --ltdl.
This patch uses the same tar piping technique to preserve the
timestamps at that end too.

I'll propose a full patch for branch-1-5 presently.

Cheers,
        Gary.

from  Gary V. Vaughan  <address@hidden>

        Preserving the installed timestamps for libltdl sources from
        `libtoolize --ltdl --copy' is pointless if they are not preserved
        from the libtool source tree at install time:

        * libltdl/Makefile.am, libltdl/loaders/Makefile.am
        (nobase_ltdldata_DATA): Renamed to...
        (ltdldatafiles): ...this.
        (install-data-local): New rule to install libltdl tree with tar to
        preserve timestamps.
