Our next meeting will be on Fri May 6, 2022 at 15:00 UTC

We will be discussing the following papers:

WG14 N2888 (http://www.open-std.org/jtc1/sc22/wg14/www/docs/n2888.htm)
Require exact-width integer type interfaces
Proposes changes to the definition of the intmax_t and uintmax_t
typedefs so that extended exact-width integer types do not factor into
the definition. Thus, these types are required to be large enough to
represent a `long long` type, but do not have to be widened for an
implementation to support e.g., __int128 as an extended integer type.
The author is looking for feedback on whether this approach will be a
palatable way forward given the ABI concerns around changing the size
or alignment of these types.

WG14 N2889 (http://www.open-std.org/jtc1/sc22/wg14/www/docs/n2889.htm)
Pointers and integer types
Proposes making intptr_t and uinptr_t mandatory types instead of
optional. The author is looking for feedback on whether there will be
any difficulties with this change.
