I would like to add a paper to next week's agenda at the request of
WG14 (who are meeting this week for a plenary meeting).

WG14 N2919 (http://www.open-std.org/jtc1/sc22/wg14/www/docs/n2919.pdf)
Relax requirements for variadic parameter lists
This paper proposes allowing a function signature consisting solely of
an ellipsis in C (e.g., void foo(...);) and changes the va_start macro
so that its second argument is optional and never evaluated (only the
first parameter is used). The author is looking for feedback on
whether this proposal will cause compatibility concerns, as WG14 is
intending to add this feature to C23.

Sorry for the late notice about the paper!
