I can do that. However now that backward compatibility is left intact I think
it would not be that bad to merge it into master and fix things on
master. the libtool
2.4 would have DEFAULT_PREFERENCE = "-1" by default it wont be picked by anyone.
with the number of developers we have it will get better testing before we
accumulate too many changes on a branch. Secondly there might be changes like
gnutls one where the patch is only valid for new libtool and should be tested
in old and new way. If there is any breakage introduced in existing build will
be caught quickly. Where as on branch resources might be divided and it may
not progress so well. I am just weighing efforts Vs. risk here and
risk seems low

Thanks
