It is correct to define WIN32_LEAN_AND_MEAN - should be well described 
in MSDN.

I agree that build with -Werror is too restrictive.

It is more correct do not define WIN32_LEAN_AND_MEAN in libxml and/or 
libxslt code. Better is configure.ac and respective configuation file 
for msvc to define such macro.
