install development versions of gmp, mpfr, mpclib on the build system
(installing libmpc-dev on debian-based pulls all needed libraries)
alternatively also install ppl and cloog-ppl (libcloog-ppl-dev on debian-based)

sources for all of the above can be found in http://mirrors-us.seosue.com/gcc/infrastructure/

get binutils, gcc-core, gcc-g++, mingwrt, w32api

extract all
ln -s w32api-*/ w32api # "w32api" symlink to the extracted dir; needed by mingwrt's compilation
                       # you can alternatively just rename the folder

build binutils with ./configure --target=i686-mingw32 --prefix=/usr

# NOTE: it *has* to be built from outside due to build system bugs that upstream refuses to fix
# NOTE: the --disable-shared --enable-static *are* mandatory here; lack of them will cause a linking error
mkdir gccbuild
cd gccbuild
configure gcc with /path/to/extracted/gcc/configure --target=i686-mingw32 --prefix=/usr \
                                                    --enable-languages=c --disable-shared --enable-static
install gcc with make && make install

APPLY http://oss.netfarm.it/mplayer/misc/mingwrt_file64.diff to mingwrt

# copy all header files to the system include dir
mkdir /usr/i686-mingw32/include
cp w32api/include/* mingwrt*/include/* /usr/i686-mingw32/include/

install w32api with ./configure --prefix=/usr/i686-mingw32 --host=i686-mingw32
install mingwrt with ./configure --prefix=/usr/i686-mingw32 --host=i686-mingw32

# TODO: check if building mingwrt before w32api 1) works, 2) eliminates the header copy step

reconfigure, rebuild and reinstall gcc with --enable-languages=c,c++

*ALL* packages other than gcc and binutils need to be installed with
    --prefix=/usr/i686-mingw32 --host=i686-mingw32

Add "--disable-shared --enable-static" as desired :)

DIRECTX:

get all .h from http://git.gnome.org/browse/ekiga/tree/win32/directx/
put in /usr/i686-mingw32/include/
