[LLVMdev] llvm-gcc build fail on RHEL v4 x86_64

[Zhongxing Xu]

The machine is a Dell workstation with xeon processors. The OS is RHEL 4 AS
x86_64
gcc version is 3.4.6

I checked out the llvm-gcc from svn, configured with
../llvm-gcc/configure --prefix=$HOME/llvm-gcc-install
--enable-llvm=$HOME/llvmobj/ --enable-languages=c,c++ --enable-checking
--disable-shared --disable-multilib

and get the following error message:

And after I run
make install
I get only c++ and g++ in my llvm-gcc-install directory.
