Just for my own edification: What's an example of a system that
doesn't "handle variadic functions very well"? I assume you're
talking about some embedded platform, but beyond that I can't guess.
I would have thought that any C compiler would pretty much *need* to
implement variadic functions; if a compiler is missing that part of
the C standard, then mightn't it also be missing a bunch of other
stuff that Csmith tries to test?
