Trivial reproducer; compile with clang -c -fno-operator-names

If a C++ program uses names such as 'and', 'xor', etc that collide with C++
reserved operator names, it won't compile unless you use the
-fno-operator-names command line option.

clang implements this option, but unfortunately when you invoke clang with -c,
the -fno-operator-names parameter isn't passed through to the compiler, and
instead prints the following warning, and fails to compile correctly.

clang: warning: argument unused during compilation: '-fno-operator-names'


The attached diff fixes this on trunk. Hopefully this is the right way to do it
and it can be applied directly.
