I"m getting build errors I think from one of your patches O tjoml.
You need to have a build area that builds with clang and does warnings as errors to avoid these issues on putback.
here is my configure step for example:
/home/rkotler/llvm_trunk/configure --enable-werror --prefix=/home/rkotler/ll
vm/install CC=/home/rkotler/llvm_3_2/install/bin/clang CXX=/home/rkotler/llvm_3_
You should run debug and retail builds too because the warnings can become serious if there is something used in a DEBUG that is only referenced there.
