this definition.  It fixes gnome for starters.  I haven't tried *emacs yet.
Like IA64, amd64 uses registers for the first few arguments and then

value is lost and its just pushed on as an 'int' in a varargs call.
When the consumer walks the list and expects to pull off void * pointers
via va_arg, then all hell breaks loose.
