Patch 1

I've been able to get libnice to compile using mingw and gcc 4.4.0 on windows xp. It involved a few patches and then a script to do the rest. This was very quick and dirty - if you wanted to incorporate it, you would probably want to clean it up a bit. I didn't want to get into modifying the makefile, so this is just an example bash script (mine's a bit diff. due to how I have things configured):

CFLAGS="-D_SSIZE_T_ -D_WIN32_WINNT=0x0501 -I<SourceDir>/stun/"
LDFLAGS="-lwsock32 -lws2_32"
./configure --disable-static --enable-shared
make
	
#Create a shared library from the archive
cd "nice/.libs"
dlltool --export-all-symbols -D libnice-0.dll -l libnice.dll.a -z in.def libnice.a
ranlib libnice.dll.a
gcc -shared -s -mwindows -def in.def $LibFlags -o libnice-0.dll libnice.a -liphlpapi -lwsock32 -lws2_32 -lglib-2.0 -lgobject-2.0
	
cd "../../"
make install

cd "nice/.libs/"
cp -f libnice.dll.a ../../
cp -f libnice-0.dll ../../

lib.exe /name:libnice-0.dll /out:nice.lib /machine:$MSLibMachine /def:in.def
cp -f nice.lib ../../
	
#Update .la to reflect shared lib we created
cd "<InstallDir>"
sed -e "s/library_names=''/library_names='libnice.dll.a'/g" -e "s/old_library='libnice.a'/old_library=''/g" -e "s/dlname=''/dlname='..\/bin\/libnice-0.dll'/g" libnice.la > libnice.mod.la
mv -f "libnice.mod.la" "libnice.la"
