It sounds like those parameters should be added only to CFLAGS, not to CXXFLAGS. __global_compiler_flags already contains things that cause warnings from the Ada and Fortran compilers. The Ada packages get the warning “'-Werror=' argument '-Werror=format-security' is not valid for Ada” over and over. It doesn't break any builds but it's annoying noise in the build logs. It would be better if __global_compiler_flags would contain only language-independent parameters, and language-specific parameters were added in build_cflags and build_cxxflags. Björn Persson
