In the future, it may make sense to avoid cascading errors from

This change here only changes the kind of the diagnostic, not
its wording or consequences.
Maybe this change should be added to the GCC 14 release notes.
Can you be more specific? Florian wrote about it in detail at
https://gcc.gnu.org/gcc-14/porting_to.html#c.
If you're referring specifically to the cascade-affecting-diagnostics,
that change hasn't been made yet.
What am I missing?
I searched for "implicit-function-declaration" at
https://gcc.gnu.org/gcc-14/changes.html
and found nothing. All right, the
https://gcc.gnu.org/gcc-14/porting_to.html
has a description, but this is one step away from the release notes.
Maybe something like this could be added to the release notes:
