I read this as CRuntime_DigitalMars, which prompted a search that led me to a page at MSDN on _alloca, which gave me a compiler error when I prototyped it, which led to my prototyping alloca for CRuntime_Microsoft and finding success, which has now confirmed my worry that publishing without a review was a bad idea. I've updated the post. Thanks!
alloca() being a compiler intrinsic means the version should be about the host compiler, not the particular runtime (though they usually go together, but not always).
