The following works for me in cygwin, NB I don't try to install in another 
directory as you are doing. I don't patch for m128 as i'm not using it at 
the moment.

In this order (binutils must be built first!)

binutils 2.11.2
---------------
configure --target=avr
make
make install


gcc-3.0.3
---------
../gcc-3.0.3/configure --target=avr --enable-languages=c
make
make install


avr-libc-20020203
-----------------
doconf
domake
domake install

The binaries and library files will end up in /usr/local/avr (default) with 
sym links for the binaries from /usr/local/bin

After un-taring the gcc-core-3.0.3 source (no need to get the whole gcc 
source as you only want the c language) apply the patch, only then can you 
configure & build.  The patch is for the source code.

Hope this helps a little.
