This question is not appropriate for the mailing list gcc@gcc.gnu.org, which is for the development of GCC itself. It would be appropriate on the mailing list gcc-h...@gcc.gnu.org. Please take any followups to gcc-help. Thanks. The trick to find out if a -Wno- option is supported is to force a compiler error. E.g., echo xx | gcc -Wno-initializer-overrides -x c - -c 2>&1 | grep 'unrecognized command line option' Ian
