Make configure & Makefiles use CFLAGS/CXXFLAGS correctly Remove broken --enable-optimize flag from configure, since it was overriding our CFLAGS. Also update configure.in to work with newer autoconf without NEWS/AUTHORS. ===================================================================
no Werror Remove -Werror flag and do not treat warnings as errors anymore. This is a useful development flag but will cause a FTBFS whenever GCC becomes more strict.
