Ok...I added the "--disable-libssp" and "make" went further but it stops
at another error:
.....
Entering directory `/linux_source/gcc-4.1.1/host-i686-pc-linux-gnu/gcc'
gcc -c -g -O2 -DIN_GCC -DCROSS_COMPILE -W -Wall -Wwrite-strings

make[2]: *** [build/fix-header.o] Error 1
make[2]: Leaving directory

make[1]: *** [all-gcc] Error 2
make[1]: Leaving directory `/linux_source/gcc-4.1.1'
make: *** [all] Error 2
What is "make" building here? Do I have a buggy avr-as? avr-as doesn't
have the '-Qy' option...should it? Or is "make" using avr-as
incorrectly here?
Thanks.
