When I broke up the stdio code, the "support pre C99 compilers" va_copy compat
define was no longer visible to vasprintf. I didn't catch this since I no longer use such old tools. Unfortunately, some well-meaning but misguided individual decided to just cut-and-paste the macro. :-( Try to clean up the situation by putting it into a header that can be overriden by any archs that need to. If this breaks for anyone (as I said, I no longer use such old tools and so haven't tested), let me know and I'll fix it.
