Error saying cannot compute suffix while building compiler gcc-4.3.2

[Vaibhav Shrimali]

Hello,
I made some changes in the compiler gcc-4.3.2 and am currently trying
to build the compiler.
There are no compilation error in the source code. I followed the
steps specified at : http://gcc.gnu.org/install/index.html
while configuring i used the command:

root@vebs-pc:/home/vebs/gcc/gcc# export SUF=-4.3
root@vebs-pc:/home/vebs/gcc/gcc# /home/vebs/gcc/gcc-4.3.2/configure
--program-suffix=$SUF
root@vebs-pc:/home/vebs/gcc/gcc# make -f Makefile

it exits and gives the following output.. whose last few lines are:

******************************************

******************************************

I have tried configuring it:
1. without suffix
2. exporting suffix in environment variable and using that environment
variable as suffix
3. without using environment variable as suffix

but none of the above methods worked.
Please tell me where I am wrong.
Thank You.
