--- Comment #20 from Cj Welborn <cjwelborn at live dot com> ---
Has anything changed since 2017 that would let me use register_printf_specifier
and -Wformat warnings at the same time? These two features are in direct
conflict with each other. I expected a GNU extension to be compatible with a
GNU warning, and all I know to do right now is disable all of the warnings
related to format specifiers.
