# the compiler to output a warning during linking:
# clang: warning: argument unused during compilation: '-std=c++0x'
# This is caused by cmake passing this flag to the linking stage which it
# shouldn't do. It's ignored so it does no harm, but the warning is annoying and
# there's no way around the problem (the flag is correctly used during the
# compilation stage). We could use add_definitions(-std=c++0x), but this will
# break the llvm build since the flag will then be used when compiling C code
# too. Sadly there's no way around the warning.
