Future releases of GCC are planning to remove[0] default support for some old features that were removed from C99 but GCC still accepts. We can test for these changes by using the following -Werror= directives -Werror=implicit-int -Werror=implicit-function-declaration -Werror=int-conversion -Werror=strict-prototypes -Werror=old-style-definition Doing so revealed an issue with the auto/ tests in that the test programs always define main as int main() rather than int main(void) which results in a bunch of errors like build/autotest.c:3:23: error: function declaration isn't a prototype [-Werror=strict-prototypes] 3 | int main() { | ^~~~ build/autotest.c: In function 'main': build/autotest.c:3:23: error: old-style function definition [-Werror=old-style-definition] The fix was easy, it only required fixing the main prototype with find -type f -exec sed -i 's/int main() {/int main(void) {/g' {} \; Regardless of these upcoming GCC changes, this is probably a good thing to do anyway for correctness.
