"Bad Instruction" Error message while building gcc-3.2.3 cross compiler for ARM on Cygwin on Win2k

Subject: "Bad Instruction" Error message while building gcc-3.2.3 cross compiler for ARM on Cygwin on Win2k
hi,

Currently, i am using the arm-elf-gcc cross compiler 2.95.2 with
binutils-2.10.1 and newlib-1.9.0 on the Cygwin platform on Windows
2000. i found the relevant material for building these tools from
Redhat site regarding bulding it for ECos.

Now i want to upgrade my gcc cross-compiler to gcc-3.2.3. i did not
upgrade the binutils and newlib (thinkgin that they should also work
newer gcc version). 

i have run the configure script with the following command.

/src/gcc/gcc-3.2.3/configure --target=arm-elf \
--prefix=/tools \
--exec-prefix=/tools/H-i686-pc-cygwin \
--with-gnu-as --with-gnu-ld --with-newlib \
-v 2>&1 | tee configure.out

It completed successfully and i build the with the command

make -w all-gcc install-gcc \ 
LANGUAGES="c c++" 2>&1 | tee make.out


Initially, error message was reporting concerning the 'Undefined
reference to __mempcpy', so i fix that error manually doing following
changes

gcc:
	PR target/10338
	PR bootstrap/10198
	PR bootstrap/10140
	* fixinc/gnu-regex.c (regerror): Use mempcpy not __mempcpy.
	
libiberty:
	PR target/10338
	PR bootstrap/10198
	PR bootstrap/10140
	* getopt.c (exchange, _getopt_initialize): Use mempcpy not
	__mempcpy.
	* regex.c (regerror): Likewise.


(i found this materail from some mailing list)

When i build the compiler again with the same command. After running
'make' command following error message were reported.

i cant see any apparent reason for these errors. 

Kindly help me in this regard. 
Should i need to apply some patches (as it was instructed on redhat
site for building gcc-2.95.2)

Regards, 
Amir Amin
