Hi Warren,

You have the -m32 flag set, but it's still giving you this:

> Warning: Generation of 64-bit code for a 32-bit processor requested.
> Warning: 64-bit processors all have at least SSE2.

But are you sure you want to compile the LLVM-GCC source? You should  
use the binaries unless absolutely necessary.
