Subject: Preserving the installed timestamps for libltdl sources from
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=cd5f1b869ab67afc608b0b0a69d3821ca9b1fdf2;p=thirdparty%2Flibtool.git

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.
