1. It's not really nice, since GPL tells something about distributing
the *sources*. Anyway, XML's binary version also ships the dll ...
2. For example, non-Windows installations won't require that dll.

You can copy from the XML package:
configure.win should contain at least:
#!/bin/sh
mkdir $DPKG/libs
cp $LIB_XML/lib/libxml2.dll $DPKG/libs
and Makevars.win can make use of
${LIB_XML}/include
${LIB_XML}/lib
The name of the environment variable to the XML stuff, LIB_XML, is fixed
due to my setup on the machine that build the Windows binaries.
