-/* We would like to have vasprintfN(), but it is difficult because you
-   can't run through a va_list twice, which we would want to do: once
-   to measure the length; once actually to build the string.  On some
-   machines, you can simply make two copies of the va_list variable in
-   normal C fashion, but on others you need va_copy, which is a
-   relatively recent invention.  In particular, the simple va_list copy
-   failed on an AMD64 Gcc Linux system in March 2006.
