I think this is a good idea. I came up with a patch (below). I noticed
one more thing: after I applied this patch, I had to regenerate
Makefile.in's by running the reconf script. After that the examples
stopped building:
/bin/sh ../libtool --tag=CXX --mode=link g++ -g -O2 -pthread -o \
CreateDOMDocument src/CreateDOMDocument/CreateDOMDocument.o \
../obj/libxerces-c.la -lnsl -L/usr/lib -licuuc -licudata -L/usr/lib \
-licuuc -licudata
g++ -g -O2 -pthread -o .libs/CreateDOMDocument \
src/CreateDOMDocument/CreateDOMDocument.o ../obj/.libs/libxerces-c.so \
-lnsl -L/usr/lib -licuuc -licudata
/usr/bin/ld: warning: libXercesMessages3_0_0.so, needed by
../obj/.libs/libxerces-c.so, not found (try using -rpath or -rpath-link)
../obj/.libs/libxerces-c.so: undefined reference to `XercesMessages3_0_0_dat'
The only difference that I can see in libxerces-c.la compared to the
one built before running reconf is the different version of libtool
being used (1.5.23a vs 1.5.25). I also remember the original version
of libtool linking to libXercesMessages3_0_0.so explicitly while the
later one does not do this. Seems like the behavior of libtool has
changed (I assume that because libxerces-c.so is linked to
libXercesMessages.so, libtool thinks that it does not need to link
to libXercesMessages.so explicitly, which makes sense). Not sure
what to do about all this.

Ah, I see. I guess this shouldn't be a big problem as long as
libxerces-c.so links to libXercesMessages.so and the application
developer does not need to link to it explicitly (at least not in
case of shared library).

Got it. Do you know what needs to be done to make Cygwin work?
Thanks,
Boris
