make error in libstdc++-v3/libsupc++

[yuchape]

Hi,
This is the problem I encountered in the "make" stage of gcc installation.
My system is x86_64-redhat-linux (Red Hat Linux 3.2.3-56).
The configure command is "--prefix=/usr/local/gcc-4.5.2
--enable-threads=posix --disable-checking --disable-multilib
--enable-languages=c,c++,fortran --with-gmp=/usr/local/gmp-5.0.1
--with-mpfr=/usr/local/mpfr-2.4.2 --with-mpc=/usr/local/mpc-0.8.1".

Please help me.
