[9fans] abaco in linux

[trebol]

In linux gcc cries:
io.c:23:7: error: assignment to expression with array type
  arg2 = va_arg(*arg, va_list);

I have seen other errors like that in the web, and solutions involving
va_copy().  I don't know... I'm just learning but the source seems
correct, arg2 is a va_list, and va_arg(*arg, va_list) expand to a va_list,
doesn't it?.  Anyway:
