Yes, I verified this. I installed into the real filesystem instead of
the .instdir and then relinking works well.

That was the same point, I did the build inside the sourcedir and
installed it directly in my real system.
Now I see:
(cd /sourcecode/XML/new/libxml2-2.4.23/python; sh ../libtool \
--mode=relink i686-pc-cygwin-gcc -O2 -o libxml2mod.la -rpath \
/usr/lib/python2.2/site-packages -module -avoid-version -L../.libs \
libxml.lo types.lo libxml2-py.lo ../libxml2.la \
---------------------------- This is still correct...
libtool: link: warning: `/lib/libiconv.la' seems to be moved
i686-pc-cygwin-gcc -shared .libs/libxml.o .libs/types.o \
.libs/libxml2-py.o -L/lib \
--------------------^^^^^^^Wrong flag 1!!!
-L/sourcecode/XML/new/libxml2-2.4.23/.libs -L/usr/lib -lxml2 \
-------------------------------------------^^^^^^^^^Wrong flag 2!!!
-L/usr/lib/python2.2/config -lpython2.2 -o .libs/cygxml2mod.dll \
Where do the flags come from? Robert, is there a verbose or debug
option for libtool?
