    Hi!
    
    I just managed to compile SDL for Windows CE using the "mingw32ce"
    configuration of http://cegcc.sourceforge.net. Test programs work as expected
    (except for those using signals -- no POSIX on mingw32ce), and I didn't yet
    encounter any problem.
    
    While it was a pain to get everything compiled and running, the changes to
    SDL are actually quite small (see attached SDL-ce.diff).
    
    Unfortunately, the win32 headers shipped with cegcc are not 100% correct, and
    it feels quite messy to work around them in SDL code, so those headers will
    also need to be patched. (Attachment: win32api-ce.diff)
    
    Since I had to apply the libtool patch from the cegcc patch, I have also ad ded
    my copy of aclocal.m4 for SDL. I had to modify the cegcc libtool patch to
    use "lt_cv_deplibs_check_method=pass_all" for mingw32ce, otherwise libtool
    would not recognize the import libraries as valid for dynamic linking.
    
    All these changes should not affect non-WinCE builds, so they could be
    included in mainline SDL.
    
    If you need some docs, you can use this description for a cross-compilation
    README:
    
    1) get cegcc from http://cegcc.sourceforge.net
    2) build and install the "mingw32ce" variant (see cegcc installation docs)
    3) patch w32api-headers (if not yet included in cegcc)
    4) setup environment (customize the first three lines as you like):
    PREFIX=/opt/mingw32ce
    TARGET=arm-wince-mingw32ce
    BUILD=`uname -m`-pc-linux-gnu
    export PATH="$PREFIX/bin:$PREFIX/$TARGET/bin:$PREFIX/local/bin:$PATH"
    export CFLAGS="${CFLAGS:- -O2 -g} -I$PREFIX/local/include"
    export CPPFLAGS="${CPPFLAGS:- -O2 -g} -I$PREFIX/local/include"
    export CXXFLAGS="${CXXFLAGS:- -O2 -g} -I$PREFIX/local/include"
    export LDFLAGS="${LDFLAGS:- -O2 -g} -L$PREFIX/local/lib"
    export HOST_CC="gcc"
    export CC="$PREFIX/bin/$TARGET-gcc"
    export CXX="$PREFIX/bin/$TARGET-g++"
    export LD="$PREFIX/bin/$TARGET-ld"
    export AS="$PREFIX/bin/$TARGET-as"
    export AR="$PREFIX/bin/$TARGET-ar"
    export RANLIB="$PREFIX/bin/$TARGET-ranlib"
    export CONFIG_SHELL="/bin/sh"
    5) build and install
    ./configure --target=$TARGET --host=$TARGET --build=$BUILD
    make
    make install
    6) use (4) and (5) for any SDL-using software you want to cross-compile
    7) copy $PREFIX/local/bin/SDL-1-2-0.dll into your executable directory on the WinCE machine
