Hmm...  That's bad.  The configure code I was talking about was not in
libtool itself, but in Kaffe, and possibly elsewhere.  I wouldn't like
to see such a big change in AC_PROG_LIBTOOL, even though looking at
the libtool script isn't precisely part of the public interface of
libtool.  But then, `libtool --config' can and should be used to
expose configuration details of libtool at configure time.

Besides, I dream of some day being able to use libtool for link tests
in configure.in, so that libtool libraries are handled properly.  By
delaying the generation of the libtool script, we forbid such uses.

IMO, the right way to deal with this problem is to generate everything
in a temporary file and rename it when you write out the last bit of
it.
