llvm dev - Sep 2011 - [LLVMdev] Still Build Errors

I am still seeing build errors with -Werror:

[off-dbg]    : [llvm] /ptmp/dag/llvm/official/llvm/lib/Support/APInt.cpp: In
function 'unsigned int getDigit(char, uint8_t)':
[off-dbg]    : [llvm] /ptmp/dag/llvm/official/llvm/lib/Support/APInt.cpp:57:
error: comparison between signed and unsigned integer expressions
[off-dbg]    : [llvm] /ptmp/dag/llvm/official/llvm/lib/Support/APInt.cpp:61:
error: comparison between signed and unsigned integer expressions

I believe this is the culprit:
