Cross compile build problems

I am trying to put together some GNU tools for embedded development. We are
working on a Motorola coldfire 5206e (among others) and I'd like to use
non-commercial tools for development. The target is a microcontroller
without an OS.

I am on a WindowsXP system with the Cygwin library installed. I am using
the following process to build the tools. All of this is done in my
/cygwin/home/brose directory

1) Download the source tarballs into coldfire/archive
2) Extract the sources into coldfire/src
3) Build and install binutils (works fine) like this
    cd $HOME/coldfire
    mkdir builds
    mkdir builds/binutils
    mkdir bins
    mkdir bins/binutils
    cd builds/binutils
    ../../src/binutils-2.15/configure --target=m68k-elf
--prefix=$HOME/coldfire/bins/binutils/ -v
    make all install

4) Attempt to build and install gcc like this
    cd $HOME/coldfire
    mkdir builds/gcc
    mkdir bins/gcc
    cd builds/gcc
    ../../src/gcc-3.4.2/configure --target=m68k-elf
--prefix=$HOME/coldfire/bins/gcc/ -v
    make all install

And I get this...

make[1]: *** [crtbegin.o] Error 1
make[1]: Leaving directory `/home/brose/coldfire/tools/build/gcc/gcc'
make: *** [all-gcc] Error 2

I've tried the --with-as=$HOME/coldfire/tools/bins/bintuils/bin/m68k-elf-as 
with no luck.

Has anyone built the current compiler on/for Windows with a m68k target in 
mind? Pray tell, what was the procedure?

Thanks in advance,
