This part has been fixed during 5.99.x btw. If you have a compiler,
which doesn't support provide the GCC builtins (which are supported by
~all compilers of relevance), you can just define them yourself and
sys/stdarg.h will use them.

The only reason in C89 to ever mess with the internals of va_list was
the lack of a copy operation. That's been fixed by C99. Everything else
is now just an excuse to write broken code.
