Just wanted to say thanks for being so thorough in describing the compilation flags, versions, etc. It's really refreshing :) You also just may want to s/gcc/clang/, none of the gcc compile commands you are running are using gcc, they are all clang/llvm. Apple just aliased the gcc binary to clang on macs.
