curl is one of those projects that's probably meant to be ultra-portable, though, working across an incredibly wide range of platforms, some probably with comparably ancient compilers. I don't actually know any details so I don't want to presume, but it wouldn't surprise me at all if targeting later standards simply isn't an option for the curl project due to portability. It may be that the (sizeof(t) == n) trick may just be what consistently works across all targets. (Until yours came along.) I do remember when configure etc. still had to check whether ANSI prototypes (as opposed to the original K&R style declarations) were supported... I hope that check isn't much of a thing anymore.
