va_start, va_arg, and va_end go babck to C89/C90. va_copy was
introduced in C99. There could be compilers that don't support it.
(Microsoft's compiler is the usual suspect for this kind of thing,
but apparently it does support it.)
I haven't studied the code; I wonder if you can modify it to avoid
using va_copy (if you care about pre-C99 portability).
