Hi!
This is the latest version of the patch in
http://lists.gnu.org/archive/html/libtool-patches/2008-08/msg00057.html
with some adjustments based on the comments further down in
the monster thread (just follow "next by thread" from the above
link).
The question that remains as far as I can tell is if it's ok to
not involve $LD.
I think it's ok to leave $LD out of it. So, ok to push?

* libltdl/m4/libtool.m4 (_LT_LINKER_SHLIBS)
[cygwin, mingw, pw32, cegcc] <cl*>: Indicate that reloadable
objects does not work.
* tests/duplicate_conv.at: Skip last test if reloadable
objects does not work.
* doc/libtool.texi (libtool script contents): Document how to
indicate that reloadable objects do not work.
