Actually the file INSTALL.win32 is up to date but doesn't describe how to 
get/install a gcc cross-compiler unless you are running debian (doc/
Cross-Compile-Howto.txt is indeed really outdated).

No need to compile ffmpeg yourself as I provide already compiled versions of 
all the 3rd party libraries we use (unless you need a more recent ffmpeg).

I recently compiled a mingw gcc 3.3.1 cross-compiler so you should be able 
to use this: "http://www.videolan.org/pub/testing/win32/
mingw-gcc3.3.1-linux-crosscompiler.tar.bz2"
You'll need to run a glibc >= 2.3.2 though.

Just extract the archive in your root directory (will put everything in /
usr/local/mingw) then download and extract the 3rd party libraries package: 
"http://www.videolan.org/pub/testing/win32/
contrib-20030824-win32-bin-gcc3.3.1-only.tar.bz2"

Once this is done, you can compile VLC with the following commands:

./bootstrap

PATH=/usr/local/mingw/bin:$PATH \
CPPFLAGS="-I/usr/win32/include -I/usr/win32/include/ebml" LDFLAGS="-L/usr/
win32/lib" \
CC=i586-mingw32msvc-gcc \
   ./configure --host=i586-mingw32msvc \
    --build=i386-linux \
    --disable-sdl --disable-gtk \
    --enable-nls \
    --enable-mad \
    --enable-ffmpeg --with-ffmpeg-mp3lame \
    --enable-dvdread --enable-dvdplay \
    --enable-faad \
    --enable-flac \
    --enable-theora \
    --with-wx-config-path=/usr/win32/bin \
    --with-freetype-config-path=/usr/win32/bin \
    --enable-mostly-builtin \
    --enable-quicktime

PATH=/usr/local/mingw/bin:$PATH make

Hope you'll find this helpful,
