[LLVMdev] fail to build LLVM GCC front-end

[Jiandong Wang]

I followed the instructions in llvm_gcc's README.LLVM file, but not exactly
the same.

the following is what I have done with LLVM:
./configure --disable-optimized --enable-checking
make
make install
(Successful)

now the llvm-gcc:
cd /home/username
mkdir obj
mkdir install
cd obj

../llvm-gcc/configure --prefix=`pwd`/../install --program-prefix=llvm-
--enable-llvm=/home/username/llvm-2.7/Debug --enable-languages=c,c++

make LLVM_VERSION_INFO=2.7
make install

the mentioned-above errors occured here.
Is something wrong?
