The C++ grammar appears to admit (and g++ accepts)

void function(...);

In such a function, how do you access any of the parameters? And what
was the motivation for allowing functions of this type where C forbids
them?

I also notice that C++ makes the comma optional, whereas it's mandatory
in C. That is, this is a legal prototype:

void function2(int ...);

What is the motivation for this change?

Followups set to comp.lang.c++

Thanks,
-Peter
