Unable to build emacs 24.4 with libxml2 on Windows

Hi list,

Please forgive me if this is not the right place to ask help for building
emacs
on Win32.

Since Emacs 24.4 has a builtin web browser (eww), I couldn't wait any
longer so
I'm trying to build it from the latest git (git commit head 165e52e, Author:
Paul Eggert <[email protected]> Date: Sun Dec 29 10:18:45 2013 -0800 Plain
copy-file no longer chmods an existing destination.) on Windows 7. I was
following the instructions in /path/to/emacs/sources/nt/INSTALL. I got
successful build as long as I don't build emacs with libxml2 (with
"configure
--without-xml2"), despite having a lot of warning messages. However, as
soon as
I removed the "--without-xml2" I was stuck. Since the builtin web browser
requires that emacs been built with libxml2, there is no point to build
emacs
without libxml2. Here is my building process:

cd /d/emacs.source
./autogen.sh
cd /d
mkdir emacs
cd emacs
/d/emacs.source/configure --prefix=/d/usr
make

My MinGW is installed in /d/usr, and MSYS in /d/usr/msys. I downloaded GTK
bundle from http://www.gtk.org/download/win32.php, unzipped and copied to
/d/usr/gtk, and added "/d/usr/gtk/bin" to PATH. Libxml2 include dir is in
GTK
bundle.

I also tried cloning libxml2 repository, checked out v2.9.1, compiled
successfully and installed to /d/usr/libxml2 but didn't help. I tried
downloading libxml2 v2.7.8 win32 from
http://sourceforge.net/projects/ezwinports/files/, unzipped and copied to
/d/usr/libxml2, then copied the directory "include/libxml2" into
"gtk/include/libxml2" (overwritting the later) but didn't help either.

Here's the errors I got from "make":
