No. This will only need, if you want to turn your C\C++ sources to LLVM
bytecode.

Original llvm-gcc is based on pre-3.4 branch of gcc. This leads to some
amount of bugs due to gcc itself. llvm-gcc4 should fix much of that
stuff, since it's based on gcc 4.0.1.

You can compile llvm-gcc (either 3 or 4) with any supported version of
gcc (pretty easy: it should be somehow fresh).
