I think that configure looks for "does this compiler support the GCC diagnostic pragma" (which clang doesn't) and doesn't enable werror by default if it doesn't exist, even though often your combination of config options and system headers won't produce the warnings that we would need the pragma to suppress. I usually add -Werror to --extra-cflags. thanks -- PMM
