Error while Building gcc 2.95.3 on AIX 4.3

Hi,
Following error thrown when I was trying to build gcc 2.95.3
------------
/usr/local/gcc_build/obj/gcc/xgcc -B/usr/local/gcc_build/obj/gcc/

I am working on AIX 4.3.3.0
The configuration options used to build gcc 2.95.3 are
--prefix=/usr/local/gcc-2.95.3
--enable-shared
--enable-threads=posix
--enable-version-specific-runtime-libs
--enable-languages=c++
--with-ld=/usr/bin/ld
--with-as=/usr/bin/as

What can be the reason of the error and how should I relolve it?

Thanks,
Abhijit.
