Error building g++ 4.8.1 on CentOS

Error building g++ 4.8.1 on CentOS

Can anybody suggest what's going wrong with my attempted g++ 4.8.1 install
on CentOS 6?
The installed compiler is g++ 4.4.7.
The make step ends shortly after this:
checking for suffix of object files... configure: error: in
`/mxhome/charrison/gcc-4.8.1/gcc-4.8.1/build-gcc/x86_64-unknown-linux-gnu/libgcc':
configure: error: cannot compute suffix of object files: cannot compile
See `config.log' for more details.
The config.log contains this seemingly-innocent remark concerning object
file suffixes:
configure:4390: checking for suffix of object files
configure:4412: gcc -c conftest.c >&5
configure:4416: $? = 0
configure:4437: result: o
The word 'error' occurs in the config.log file here (and my g++4.4 would
certainly fail the test):
configure:4936: checking whether g++ accepts -static-libstdc++ -static-libgcc
configure:4953: g++ -o conftest -g -O2 -static-libstdc++ -static-libgcc
conftest.cpp >&5
g++: unrecognized option '-static-libstdc++'
