--- Comment #5 from Alejandro Colomar <foss+...@alejandro-colomar.es> ---
Oh, for some reason I thought implicit int had been entirely removed from GCC.
It's indeed only a default error for new dialects, but not for old ones.
alx@debian:~/tmp$ cat implicit.c
main(void)
{
return 0;
}
alx@debian:~/tmp$ gcc -std=c89 -Wall -Wextra implicit.c
implicit.c:1:1: warning: return type defaults to ‘int’ [-Wreturn-type]
1 | main(void)
| ^~~~
alx@debian:~/tmp$ gcc implicit.c
implicit.c:1:1: error: return type defaults to ‘int’ [-Wimplicit-int]
1 | main(void)
| ^~~~
Hmmm. Yeah, then I guess it makes sense to keep auto around in those modes.
