But I guess this wrapper won't help much because the MS libc doesn't support, for example, the 'z' modifier. What's your plan for dealing with that? I was hoping we can just print with a larger length specifier. '%z' will there have to be disallowed and an appropriate signed/unsigned specifier should be used instead. Do you think that would be OK? If not, there are only a handful of places where we use vsnprintf()'s, so I could #ifdefs the code.
