While trying to compile coreutils with -Wextra,
I noticed many warnings due to automatic variables
initialized with { 0, }.
As I understand it, since C90 the above will initialize
[all members of] the type to that used in static scope.
I.E. the following is valid:
mbstate_t m = { 0, };
int i = { 0, };
struct { int a; int b; } s = { 0, };
It would be great I think if gcc would relax this
warning in the specific case where { 0, } is specified.
I.E. with a trailing ',' as that would be clear indication
that one wants to init all elements to 0, and that
we haven't just forgotten some members.
