--- Comment #4 from Jonathan Wakely <redi at gcc dot gnu.org> --- (In reply to Agostino Sarubbo from comment #0) > Fedora (there are other unrelated patches): > https://download.fedoraproject.org/pub/fedora/linux/development/rawhide/ > Everything/source/tree/Packages/g/gcc-13.2.1-5.fc40.src.rpm Fedora GCC doesn't change defaults from upstream. Flags like -D_FORTIFY_SOURCE=3 are added by the Fedora build system when building RPMs, they are not hardcoded as defaults into gcc itself.
