Can you please limit it to the clang case? Add an internal variable that either contains -Werror or nothing, depending on the compiler. What I fear is that if we use -Werror unconditionally and the user (or some automated build system) decides to add some silly option to KCFLAGS, we will get silent failures in the cc-option tests. Of course, the same can happen with clang, but there seems to be no way around it. BTW, is there a chance that this would be fixed in some later clang version? Accepting unknown commandline options is a rather unusual behavior. How are all the ./configure scripts going to cope with it?
