We will be discussing the following papers:

P2310R0 Revise spelling of keywords (https://wg21.link/p2310r0)
Suggests unifying the spelling of some keywords in C to match the same
spelling used in C++. The keywords involved are: _Alignas, _Alignof,
_Bool, _Static_assert, and _Thread_local. The author is especially
interested in hearing about existing semantic differences between C
and C++ with these keywords that may cause problems for users using
the proposed new keywords in a file compiled separately as C and C++.
The author would like people to have read WG14 N2850 _Thread_local for
better C++ interoperability with C
(http://www.open-std.org/jtc1/sc22/wg14/www/docs/n2850.pdf) as it
relates to P2310R0.

P2338R1 (https://wg21.link/p2338r1) Freestanding Library: Character
primitives and the C library
Proposes requiring much of the C library (and C portions of the C++
library) to be available in freestanding implementations in C++. This
includes many of the character/string based functions (strcpy, memcpy,
etc). This paper was previously discussed at the June 2021 SG22
meeting. The author is especially interested in feedback around the
wchar_t functions.
