Problems between cygwin and window's cmd about making GCC (options.h)


I must write a batch file to call a shell script in cygwin for making
GCC toolchains for some purposes.
After making binutils successfully, I make gcc-3.4.3 using my batch file...

My batch file:
CLS
@echo off
set MAKE_MODE=UNIX
sh ./test.sh
test.sh:
#!/bin/bash
cd /cygdrive/c/toolchains/build-gcc
sh ../gcc-3.4.3/configure --target=arm --srcdir=../gcc-3.4.3
--prefix=/usr/local  --enable-languages="c"
make
make install

It's work fine (make success) when I directly run test.sh in cygwin,
but there are some error as follow when I run my batch file to call
test.sh.

I have set my PATH=c:\cygwin\bin, but it also have error, anyone can
give a help? Thanks very much.
