Disclosure: I've got zero C/C++ on my resume. I was asked to diagnose a kernel panic and backport kernel security patches once, but it was very uncomfortable. ("Hey, Terr knows the build system, get him to do it...") That said, perhaps something like disabling the default -fextended-identifiers [0], and enabling the -Wbidi-chars [1] warning.

Cool, the latter was added to fix CVE-2021-42574: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=103026
