--- Comment #1 from David Malcolm <dmalcolm at gcc dot gnu.org> ---
Thanks for filing this.
Confirmed.
Presumably we should print something like:
a.c:1:9: error: ‘INT_MAX’ undeclared here (not in a function)
int i = INT_MAX;
^~~~~~~
a.c:1:9: note: 'INT_MAX' is defined in header '<limits.h>'; did you forget to
'#include <limits.h>'?
+#include <limits.h>
(note the fix-it hint)
FWIW this looks close to being covered by this (not-yet-in-trunk) patch:
https://gcc.gnu.org/ml/gcc-patches/2017-05/msg00438.html
(Presumably we'd want it for the C++ FE also; presumably recommending <climits>
rather than <limits.h> there)
