OK to commit?
The AB_INIT invocation causes something like this extra info to appear
in the configure output:
configure: autobuild project... GNU Libtool
configure: autobuild revision... 2.2.11a (1.3227 2010-08-09)
configure: autobuild hostname... fuchs
configure: autobuild mode... default
configure: autobuild timestamp... 20100822T183040Z
When you don't have autobuild installed, thus AB_INIT not defined,
the patch should be a no-op. autobuild will still be usable without
the above output, it's just that the developer then needs to explicitly
provide the information as command-line arguments to autobuild.
I'd rather avoid adding libltdl/m4/autobuild.m4 to our git, that might
introduce version conflicts in the future.
A better long-term solution would be to start using gnulib-tool (for
argz, autobuild, maybe eventually bootstrap), but I *really* don't want
to start experimenting with that option before the release.
Thanks,
Ralf
configure: use Autobuild AB_INIT if available.
* configure.ac: Call AB_INIT if it is defined, with
$autobuild_mode as argument, to be set at configure time.
Set AB_VERSION to the Libtool version string.
* HACKING: Update.
* libltdl/m4/.gitignore: Ignore autobuild.m4.
