Fix warnings for GCC as well
GCC ignores __attribute__((unused)) when compiling C++ code. (Yes, this is true)
GCC -Wmaybe-uninitialized just gives false positives in my experience,
so drop it. However, this exposed a problem with AX_APPEND_COMPILE_FLAGS
and clang. clang gives a warning, but not an error, when given a -Wno-UNKNOWN-FLAG.
So add -Werror as an extra flag to make clang fail on unknown -Wno-UNKNOWN-FLAG
