Documentation on known differences should be updated.

DMD on 64bit has a runtime library implementation that retrieves the next variadic argument based on it's TypeInfo and it's tsize().

eg:  auto va = va_arg(ap, ti);


GDC uses it's GCC's built-in VA_ARG_EXPR, which depends on the type being known at compile time in order to work.

eg: auto va = va_arg!(Foo)(ap);


There is no way around this other than implementing a new runtime function which does a similar job that DMD's implementation does, but have it specific for the way GDC passes variadic arguments to the callee.
