 the MingW cross-compiler for windows is quite old and there is currently
 no cross-compiler for Windows 64. Packages for both would be fantastic!

 == Ports ==

 The ports have to be compiled in the following order:
 * ~~{i686,x86_64}-w64-mingw32-binutils~~ (DONE)
   * (no dependencies)
 * ~~{i686,x86_64}-w64-mingw32-headers~~ (DONE)
   * (no dependencies)
 * ~~gmp, mpfr, libmpc~~ (native ports already packaged by MacPorts)
 * cloog, ppl (might be worth looking into)
 * {i686,x86_64}-w64-mingw32-gcc (possibly rename)
   * gcc compiler
   * dependencies:
     * {i686,x86_64}-w64-mingw32-binutils
     * {i686,x86_64}-w64-mingw32-headers
     * {i686,x86_64}-w64-mingw32-gcc
     * gmp, mpfr, libmpc
     * libiconv, zlib
   * the first stage compiles (this is a standalone gcc, it won't actually
 be able to link executables, but it is already suitable to compile the
 CRT)
 * ~~{i686,x86_64}-w64-mingw32-crt~~ (DONE)
   * dependencies:
     * {i686,x86_64}-w64-mingw32-binutils
     * {i686,x86_64}-w64-mingw32-headers
     * {i686,x86_64}-w64-mingw32-gcc (either first stage or any later
 stage)
   * make sure that all the file are where expected
 * {i686,x86_64}-w64-mingw32-libgcc
   * same sources as the gcc compiler; only a different target (`make all-
 target-libgcc && make install-target-libgcc`)
   * when a compiler already exists, one could build both gcc and libgcc at
 the same time
   * files provided by the gcc port should be removed
   * dependencies:
     * {i686,x86_64}-w64-mingw32-crt
     * {i686,x86_64}-w64-mingw32-gcc (either first stage or any later
 stage)
 * pthreads-win32
   * dependencies:
     * {i686,x86_64}-w64-mingw32-libgcc (or full compiler)
 * {i686,x86_64}-w64-mingw32-all(?) (second stage of gcc compiler)
   * same sources as the gcc compiler; only a different target (`make &&
 make install`)
   * dependencies:
     * pthreads-win32
     * {i686,x86_64}-w64-mingw32-libgcc

 == Things to do ==

 * fix layout of individual packages (folders where files are installed)

 == Further challenges ==

 * on top of C and C++ also support Ada, Fortran, ObjC, ObjC++ (`--enable-
 languages=c,c++,objc,obj-c++,ada,fortran`)
 * support clang
 * figure out where `stdlibc++` should be located on Windows (is it
 possible to build it statically?)
