Subject: C89 question: Do we need to accept -Wint-conversion warnings
Date: Tue, 10 Oct 2023 13:29:48 +0200	[thread overview]
Message-ID: <87h6myaf6b.fsf@oldenburg.str.redhat.com> (raw)

Are these code fragments valid C89 code?

  int i1 = 1;
  char *p1 = i;

  char c;
  char *p2 = &c;
  int i2 = p2;

Or can we generate errors for them even with -std=gnu89?

(It will still be possible to override this with -fpermissive or
-Wno-int-conversion.)

Thanks,
Florian
