The clang compiler accepts *any* compiler flags, and just reports an annoying warning instead: warning: unknown warning option '-Wsomething' [-Wunknown-warning-option] Use -Werror=unknown-warning-option to change this warning into an error, and detect the unsupported flag. Since this is a clang specific option, it can't be used unconditionally with other compilers. The option is also only used for checking the compiler flags, and not for compiling the code.
