By default clang will return echo a warning if an option is unknown. Therefore turn warnings into errors when polling for options.
As far as I tested with clang 3.5 on Ubuntu 14.04, it looks different.
$ clang -fno-delete-null-pointer-checks helloworld.c clang: error: unknown argument: '-fno-delete-null-pointer-checks' $ echo $? 1
Possibly it depends on how the clang/LLVM toolchain in use has been built and configured. In any case, explicitly turning warnings into errors fixes those toolchains which only emit warnings for unknown options, and it won't harm those such as the one above which already do "the right thing".
