Interesting.  That option doesn't seem to do anything on my Mac's compiler
either (Apple LLVM version 8.0.0 (clang-800.0.42.1)).  However, it surely
spews a metric buttload of warnings with RHEL6's gcc.  Points up my
concern upthread about different peoples' compilers interpreting these
less-common switches differently.
