Sold!  Please apply.

Are you sure that aclocal sorts m4 input alphabetically? I wouldn't be surprised if it just pulls the files from disk in directory order (equivalent to mtime I think). Or maybe they get m4_included in topographic order...

Either way, it only really affects libtool's own bootstrap, since we now remove old libtool.m4s from $prefix/share/aclocal.

This isn't a patch, it's just a new file to drop in the distribution as
m4/lt~obsolete.m4.  Ok, it needs adding to EXTRA_DIST as well, but
that's it.

Provided we bootstrap with automake 1.8 or newer it will get added automatically (by virtue of being m4_included).

I think we also don't need add it to pkgmacro_DATA, since it is just noise to libtool users, especially because it might wreak havoc if some future (or old!) version of aclocal manages to slurp it in before libtool.m4.

I think the comment I've put in it explains how it works pretty well,
basically instead of whatever you've got in
/usr/share/aclocal/libtool.m4 turning up in your aclocal.m4, you get
this instead; which is harmless because the filename is asciibetically
after anything else in m4/ so the m4_ifdef just expand to [].

Please add a comment near pkgmacro_DATA in to remind us not to install it too.

Okay to commit?
