HOW TO BUILD FOR WINDOWS

Actually, if you want to build r2 for windows, you can use native compiler with mingw32 or cygwin, but there's also the possibility to crosscompile from a Linux box:

Crosscompilation

ArchLinux

./configure --with-compiler=i486-mingw32-gcc --with-ostype=windows --host=i486-unknown-windows
make
make w32dist

cd swig
export CC=i486-mingw32-gcc
export CXX=i486-mingw32-g++
unset CFLAGS
unset LDFLAGS
export LDFLAGS="-L${HOME}/.wine/drive_c/Python27/libs ${LDFLAGS}"
export CFLAGS="-Wl,--enable-auto-import -L../../radare2-w32-0.5 ${CFLAGS}"
./configure --with-ostype=windows --host=i486-unknown-windows --with-cc=i486-mingw32-gcc --with-cxx=i486-mingw32-g++

Ubuntu

sudo apt-get install mingw32
./configure --with-compiler=i586-mingw32msvc-gcc  --with-ostype=windows --host=i586-unknown-windows
make
make w32dist

Windows x86-64

Setup toolchain

open http://mingw-w64.sourceforge.net/
wget http://switch.dl.sourceforge.net/project/mingw-w64/Toolchains%20targetting%20Win64/Automated%20Builds/mingw-w64-bin_i686-linux_20110627.tar.bz2
mkdir -p mingw64
tar xjvf mingw-w64*.bz2 -C mingw64
export PATH=$PWD/mingw64/bin:$PATH

Build radare2

./configure --with-compiler=x86_64-w64-mingw32-gcc --with-ostype=windows --host=x86_64-unknown-windows

Python bindings:

wget http://www.python.org/ftp/python/2.7/python-2.7.msi
msiexec /i python-2.7.msi
cd r2-bindings
make w32
make w32dist
