As far as I understand from [1][2]:
The way to get exactly the pertinent diagnostics is to use clang 15
with options
-std=c2x -Wincompatible-function-pointer-types
and look at all errors and warnings.
If one uses clang 15 with options
-std=c17 -Wdeprecated-non-prototype
and looks at all warnings, one gets most, but not all, of the needed
diagnostics.
If one uses GCC 12, there are not the appropriate warning options. [2]
