Bootstrap order:
 - w32api
 - mingw-runtime
 - binutils
 - gmp
 - mpfr
 - gcc
 - binutils
 - w32api
 - mingw-runtime


w32api
    ./configure --prefix=/mingw
    make
    make install


mingw-runtime
(requires w32api src in adjacent directory without version suffix)
    ./configure --prefix=/mingw
    make
    make install


binutils
    ../binutils-?.?/configure \
        --prefix=/mingw \
        --disable-nls
    make tooldir=/mingw
    make tooldir=/mingw install


gmp
    ./configure --prefix=/mingw --enable-cxx --build=i686-pc-mingw32
    make
    make install
    (do not strip libraries - instead strip before installation and rerun make)
    

mpfr
    ./configure --prefix=/mingw
    make
    make install


gcc
    ../gcc-?.?.?/configure \
        --prefix=/mingw \
        --enable-languages=c,c++ \
        --enable-threads \
        --disable-nls \
        --enable-__cxa_atexit \
        --libexecdir=/mingw/lib
        (Add --disable-werror --disable-checking for snapshots)
    make bootstrap
    make install
    rm -rf /mingw/include/c++/4.?.?/i686-pc-mingw32/bits/*.gch



Remove documentation
    rm -rf /mingw/{info,man,doc,share}

Strip files
    find /mingw/bin -type f -exec strip --strip-all '{}' ';'
    find /mingw/lib -type f -exec strip --strip-debug '{}' ';'
