[avr-gcc-list] trying to build avrgcc using cygwin

I'm not having much luck getting a patched win32 version of avrgcc going
that supports mega128 parts so I figured I'd try to build it myself. Ha. I
already had cygwin on my system so I downloaded gcc 3.0.3 and I'm trying to
configure and build it as follows:

$ cd build-gcc-3.0.3
../gcc-3.0.3/configure -v --target=avr --prefix=/cygdrive/c/avrgc/new --with
nu-ld --with-gnu-as --disable-nls > conf_gcc.log 2>&1
$ make all LANGUAGES="c" > build_gcc.log 2>&1

The configure step doesn't cause any errors but when I build it I get (at
the end of the log file):

(MAKE="make"; srcdir=`cd ../../gcc-3.0.3/gcc/fixinc && pwd` ; \
CFLAGS="-DCROSS_COMPILE -DIN_GCC    -g -O2 -W -Wall -Wwrite-strings -Wstrict

WARN_CFLAGS="-W -Wall -Wwrite-strings -Wstrict-prototypes -Wmissing-prototyp
es -Wtraditional -pedantic -Wno-long-long"; \
export MAKE srcdir CC CFLAGS LDFLAGS WARN_CFLAGS; cd ./fixinc && \
/bin/sh ${srcdir}/mkfixinc.sh i686-pc-cygwin avr-unknown-none)

This is my first time building gcc so I'm just stumbing in the dark. While I
go on trying to figure out what went wrong, could someone point me in the
right direction?

Once I can build avrgcc 3.0.3 I will try to apply patches published here to
add mega128 support. I can dream, right? :-)

BTW Anton, thanks for your help but somehow the files you sent aren't enough
to get testprograms compiled with mega128 support. I must be doing something
