--- Comment #21 from Kees Cook <kees at outflux dot net> --- (In reply to Martin Sebor from comment #20) > Well, I just "asked" for such an option the same way you asked for > -fstrict-flex-arrays in comment #3, because I believe it would be useful to > make the BOS improvements you're looking for available even to code that > can't do a whole-hog replacement of all trailing arrays with flexible array Right, sorry, I meant, "I have a project waiting to use this feature right now", where as other projects might, upon discovering this feature, decide they also only need "-fstrict-flex-arrays". e.g. what option would GCC itself use? > members. The spelling of the option names doesn't seem important to me > (they could be separate options, or the same one with an argument). How about "-fnot-flex-arrays=N" to mean "trailing arrays with N or more elements will NOT be treated like a flex array"? Then code with sockaddr can use "-fnot-flex-arrays=15", code with "[1]" arrays can use "-fnot-flex-arrays=2", code with only "[0]" arrays can use "-fnot-flex-arrays=1", and "-fstrict-flex-arrays" can be an alias for "-fnot-flex-arrays=0", which Linux would use.
