Well, it was you that introduced the code into Libtool, I only "fixed"
it, in the sense that it worked with documented Autoconf interfaces.

*snip code*

(In the example, you should have run autoheader...
or plainly: autoreconf; but I see your point)

Well, first I believed you introduced this so libltdl can work as
non-subpackage.  In _that_ case, surely libltdl needs to know the name
of the config header.  I'm not sure it would need to _call_
AC_CONFIG_HEADERS if the parent package does not use AC_CONFIG_HEADERS
itself.  I assumed you found some reason when introducing the behavior?
If not: let's just remove the call to AC_CONFIG_HEADERS in ltdl.m4.

This answers part of your question, I think.  The other part is: if
libltdl is a subpackage.  Then, fussing with AC_CONFIG_HEADERS at all is
none of our business.  :-)

Would you agree?

Cheers,
Ralf
