The code changed in the two middle hunks went out after 2.2.6 and
are thus gone in 2.2.8 and later, so that no longer applies.

I also took the liberty of changing ltmain.m4sh instead of the
generated libtool script.

So, this is a better attempt for a patch, with Andreas added to
THANKS.

Ok to push?

Cheers,
Peter
